OpenAPI Initiative Newsletter – August 2024

By Blog

Welcome to the OpenAPI Initiative August 2024 Newsletter, our regular round-up of the latest stories from across the OpenAPI landscape. It’s vacation season in the northern hemisphere, but there is plenty of news to share!

Initiative News

Our Arazzo Specification was announced in our last newsletter which, in case you missed it, is a description language that allows API providers to describe sequences of API calls, both within one API or across various APIs. The arrival of Arazzo has created a significant buzz in the community, with a great deal of interest in how Arazzo can meet many use cases.

To help introduce Arazzo we’ve started another initiative, our OpenAPI Hangouts series! We held our first OpenAPI Hangout on 30th July 2024, where Budha Bhattacharya, Frank Kilcommins, Lorna Mitchell, and Erik Wilde discussed Arazzo in detail. If you missed the Hangout, please watch the video on the event page. Keep an eye open for future OpenAPI Hangouts by following us on LinkedIn.

We also took a detailed look at Arazzo through a real use case, namely for API consumers implementing a buy-now, pay-later (BNPL) solution in their e-commerce solution. While the BNPL API and platform in our use case are examples they accurately represent the complexity of such e-commerce orchestration and workflow requirements. You can discover more about the full BNPL example on our blog.

Specification News

Our Specification website has recently undergone a revamp. All versions of the OpenAPI Specification are now provided through this page, together with v1.0.0 of Arazzo. We hope these changes will provide a focused, “one-stop” solution for readers of our Specifications.

Work continues on multiple releases of the OpenAPI Specification. We now have several releases in-flight, with 3.0.4, 3.1.1, 3.2, and 4.0 coming down the tracks.

3.0.4 and 3.1.1 are patch releases that make OAS 3.0 and 3.1 much clearer without adding any new requirements. We’ve expanded and improved explanations of parameter serialization, discriminators, reference resolution, and more. We’ve also updated our citations of security standards and improved the consistency and clarity of our wording throughout the specification.

3.2.0 will be an incremental step towards “Moonwalk” that will be strictly compatible with 3.1. Our goal is to introduce a few Moonwalk improvements along with other small fixes that will be easy for tooling providers to implement in the near future. This will help bridge the gap to the eventual release of 4.0.

Work on OpenAPI 4.0, codenamed Moonwalk, also continues apace under the auspices of the Moonwalk Special Interest Group (SIG). You can catch up with latest developments on Moonwalk Discussions, where we publish discussion points from each meeting.

Our specification meetings are, of course, open to anyone. If you want to join to listen in or contribute, you’ll find the meetings in the OAI calendar.

Community News

We recently announced our Community Heroes feature, which profiles an invaluable member of the OpenAPI community. Our second Community Hero is Frank Kilcommins, Principal API Technical Evangelist at SmartBear, who has been instrumental in creating the Arazzo Specification.

Please read more about Frank on our blog. Also let us know if you have any suggestions for a future Community Hero and we’ll do our best to feature them!

Events Round-up

Conference season is also about to ramp up again and we’ve got several OAI tracks and sessions in the pipeline.

Apidays London – 18th – 19th September, 2024

Our next event will be apidays London, where Erik Wilde will host our OAI track. The theme of apidays London is “APIs for Smarter Platforms and Business Processes”, and will focus on how AI and APIs act as enablers for businesses. Our OAI track will therefore look at standards and practices in the OpenAPI ecosystem that act as enablers for business. We’ll hear from Frank Kilcommins with an update on Arazzo, Lorna Mitchell on API governance, and Gobe Hobona on API standardization for geospatial ecosystems.

Nordic APIs Platform Summit – 7th – 9th October, 2024

The Nordic APIs Platform Summit is held in Stockholm in October each year and offers a wealth of experiences and perspectives across the API economy. OAI is offering an OpenAPI Fundamentals workshop at the Summit, with the content based on our Linux Foundation course. The workshop will be led by Budha Bhattacharya and Chris Wood, and will be an “ask me anything” format to provide you with deep insights on your target topics. Please follow the link to register.

Event Outlook

We are planning OAI tracks at the following events:

Finally…

That’s it for this newsletter. If you are in the northern hemisphere we hope you are having a great summer!

If you have any news you want to share with the OpenAPI community please get in touch by email or join the Outreach channel on Slack. We also welcome suggestions on how we can improve this newsletter or bring you information that can help make the most of how you use specifications published by the OpenAPI Initiative.

Case Study: Using the OpenAPI Specification for Integrating SaaS Applications and Scaling Up to Hundreds of API Providers

By Blog

Guest blog post by Donald Atha, Software Architect, BetterCloud

One of the biggest challenges facing IT teams today is the increase in tedious and repetitive tasks driven by the explosive growth in SaaS applications over the last 10 years. Companies are using more and more SaaS products, which presents challenges when it comes to managing employee onboarding and offboarding, managing licenses and permissions, and resolving help desk tickets. At BetterCloud, we give IT teams the tools to reduce the amount of manual work on their plate with automations and configurable workflows. As the number of SaaS applications grows, our customers rely on our library of SaaS integrations to also grow.

Testing OpenAPI Generators for Rapid Integration

Recently the Innovation Team within BetterCloud, a team tasked with discovering and testing new capabilities that accelerate innovations, took on the challenge of prototyping a solution that would allow us to more rapidly integrate with various SaaS applications and scale that solution to onboard hundreds of API providers. The team agreed early on in order to reach the ambitions of the business, we would need to automate much of the process. The team also agreed that this would be possible because much of adding a new integration is the same and that the OpenAPI Specification would allow us to automate pieces of this by using existing community generators. 

To fully understand the problem, it helps to understand what it means to add an integration at Bettercloud and a bit about our product. BetterCloud’s workflow engine automates processes like employee onboarding by detecting when a new employee is hired and subsequently granting access to the various SaaS applications required for their role. This onboarding scenario is just one of many use cases we support. All these use cases invariably necessitate ingesting and storing data from the 3rd party provider and updating the provider’s state. For instance, in the onboarding use case, the ingestion process fetches employee data, detects a change in status, and triggers the onboarding workflow. This workflow calls the provider’s APIs to create accounts or grant access to shared resources for the employee—functionality we internally refer to as “actions.”

When embarking on adding a new integration, BetterCloud begins by validating that the provider has the necessary APIs to support our use cases. This crucial step sets the stage for efficiently accessing required data and assessing whether the provider’s APIs are compatible with our action use cases. The OpenAPI Specification provides a consolidated view of this information.

Reducing the Amount of Code Written by Using the OpenAPI Specification

Once the API is understood, the next phase is implementing the ingestion logic. This phase involves calling the provider’s APIs to fetch and store all necessary data within BetterCloud’s infrastructure. The team has explored two methods to coordinate this, both leveraging the OpenAPI Specification. The intent with both approaches is to reduce the amount of code that a developer must write when adding a new integration. The first involves code-generating an HTTP client in Java using the OpenAPI Java code generator, while the other approach uses extensions to markup the spec, enabling the configuration of the ingestion logic. This marked-up spec feeds into a general-purpose engine that implements the logic based on the extensions. This covers the ingestion of data from the APIs, but once acquired, it must be stored to serve our applications. 

BetterCloud utilizes a SQL database to store the entities we ingest. To create the schemas, the team employs the OpenAPI MySQL generator, Flyway, and Terraform. These tools facilitate the creation and configuration of a database for the new provider. The team was able to slightly modify the existing mustache templates of the MySQL generator in order to add our internal fields such as customer id. Since both the ingestion data models and the MySQL data schemas derive from the OpenAPI Specification’s entities, automation of this process becomes straightforward as the data models are aligned. With just an OpenAPI definition, we can generate a new database and its schemas at the click of a button in all of our environments!

Conclusion – Better Scaling the OpenAPI Specification, Better Value

We anticipate that this approach will allow us to bootstrap the ingestion portion of adding a new integration. By automating and code-genning common elements, the team can concentrate on the unique aspects of each new integration. Much like how we at BetterCloud automate workflows for IT teams to allow them to scale the impact of their work, the OpenAPI Specification has given us the tools to build our own automations that scale the value we can provide to our customers.

WireMock, Venture Funded Open Source API Mock Platform, Joins OpenAPI Initiative as New Member

By Announcement, Blog

The OpenAPI Initiative, the consortium of forward-looking industry experts focused on creating, evolving, and promoting the OpenAPI Specification (OAS), is announcing today that WireMock has joined as a new member. Welcome WireMock!

WireMock was created in 2011 and has been a popular open source tool for API mocking. Last year, project founders Tom Akehurst and Uri Maoz launched a company with the same name. They created a managed cloud service called WireMock Cloud, and in May 2023 announced a $6.5 million investment from Ridge Ventures, with participation from First Rays Venture Partners, Scribble Ventures and several unnamed investors.

Building a stable and predictable environment when creating APIs is crucial to the efficiency and success of developers. WireMock is a flexible and free open source platform that can be run as a standalone server, or in a hosted version via the WireMock Cloud managed service.

“We are thrilled to welcome WireMock as a member of the OpenAPI Initiative! Mocking APIs plays a crucial role in reducing development time and increasing productivity for developers. The open source community relies heavily on mocking tools in order to speed up development, better test for edge cases, and much more,” said Isabelle Mauny, OpenAPI Business Governing Board Chair. “It’s important for tools makers to implement the OpenAPI Specification and mocking APIs is one of the great benefits of using the OpenAPI Specification for your APIs.”

“OpenAPI is the key standard around which a rich ecosystem of tools and infrastructure is rapidly evolving. We believe that first-class OpenAPI support in WireMock will unlock a huge amount of productivity for both API developers and consumers,” said Tom Akerhust, the WireMock creator and the CTO of WireMock Inc.

“API-first development is at the core of both the WireMock open source project and WireMock Cloud, our developer productivity platform. Support for OpenAPI is central to our mission of enabling developers to simulate APIs across the entire application lifecycle”, said Oleg Nenashev, Community Builder and CNCF/CDF Ambassador, WireMock, “We believe that our vision and products are closely aligned with the OpenAPI Initiative. We’re pleased to join OAI as a member and work on expanding the OpenAPI ecosystem together”

WebAssembly and Career Networking at Gluecon

By Blog

Guest Author: Tony Blank

Tony is an experienced software developer with an interest in web design, web marketing, customer integration, and software IT including networking, data center management, and sysadmin. He has attended many of the GlueCon events in the past years because of its highly curated content and focus on cutting-edge technology transforming the web, including API Standards. GlueCon was sponsored by the OpenAPI Initiative.

“Gluecon 2023 was an incredibly enjoyable conference. I extend my thanks to the OpenAPI Initiative for providing me with a complimentary ticket. If anyone is considering attending a future Gluecon and has any questions, please feel free to reach out.”

Email: me@tonyblank.com

Twitter: @thetonyblank

I can’t believe it’s been ten years since I first started attending GlueCon. This event has always been on my “must-attend conference list” because of its highly curated content, focusing on cutting-edge technology that is poised to transform the web. Throughout the years, I’ve had the opportunity to represent a few different companies at Gluecon leading community teams. However, this year is different. I was unfortunately laid off in March, and now I find myself in search of my next exciting challenge.

A conference like Gluecon is the perfect place for me to network and connect with innovative companies.

Back in 2013, when I first attended Gluecon, the conference was abuzz with discussions about web services and API standards. As a developer evangelist for Context.io, an email data API, I found Gluecon to be the ideal gathering to meet fellow developers and individuals keen on exploring new APIs.

This year, the main topic of conversation was WebAssembly.

For those unfamiliar with WebAssembly, it is a binary instruction format specifically designed for the web. Its purpose is to enable high-performance code execution within web browsers. These low-level languages execute on the web with near-native performance, revolutionizing the way applications are built.

It reminds me a little of when Docker was first released and it was apparent to everyone how useful containers are. In fact, Solomon Hykes, the co-founder of Docker, famously tweeted that if WASM had existed in 2008, Docker would never have been necessary (https://twitter.com/solomonstre/status/1111004913222324225).

The second time Solomon presented Docker publicly was 10 years ago at Gluecon, along with Jeff Lindsey. Jeff referred to Solomon’s quote during his talk at Gluecon titled “Futuristic Architectures: Session Backends and WebAssembly Components.” In his talk, Jeff brilliantly illustrated how standard WASM components will lead to innovative app architectures. It was a delight to catch up with Jeff, as the last time we crossed paths was in Paris at the dotScale conference back in 2014. He was showing dotScale Dokku, which began… as Jeff’s Docker demo for his Gluecon talk the previous year.

Another remarkable session was the fireside chat between Alex Williams, from The New Stack, and Matt Butcher, founder and CEO of Fermyon. Alex has been covering the most intriguing emerging technologies since his days at Programmable Web (RIP), and his conversation with Matt was no exception. Hearing about how the benefits of WASM, like cross-language compatibility and fast execution times, are being implemented by Fermyon in their new cloud offering was very exciting.

Not every talk at Gluecon was about WebAssembly. Any developer would have enjoyed Jason Harmon’s talk focused on internal API best practices. Treating APIs like products vs. a feature of a product leads to good developer experience, faster production cycles, and fewer headaches. Jason is currently the CTO of Stoplight.io, who went through the Techstars Cloud accelerator in 2015. Editor’s note: Jason was also a key figure in the early days of the OpenAPI Initiative!

It was fun bumping into Samy Fodil, who I met when his startup Sage Hero was in Techstars Cloud in 2016. Samy was at Gluecon this year talking about his current startup Taubyte and, yep, WebAssembly!

Gluecon always closes with some amazing keynotes. Unfortunately, I had to miss this year to get set up for Mile High Startups & Music, the monthly tech event I promote featuring Denver’s best local musicians. (Big shout out to Elastic for supporting both Gluecon and Mile High Startups & Music!)

I hope to see you there next year!

Tools That Support OpenAPI Specification

By Blog, News

Over the last 18 months we’ve been looking at how we can better capture data on the OpenAPI ecosystem with particular focus on tooling – what tool makers are doing, what versions of OpenAPI they support and so on. Tooling registries obviously already exist in the wild such as openapi.tools. The goal was not replicate the functionality of these registries, but to industrialize the data collection process using a mechanism that was eminently extensible and could be expanded with very limited modification.

Introducing our OpenAPI tooling registry. The registry exposes a “classic” UI based registry hosted at https://tools.openapis.org that uses data automatically sourced from existing registries and uplifted with data collected from (as a first cut) the Github API. This mechanism was proven by Mike Ralphson and used to publish https://apis.guru/awesome-openapi3/, and we’ve taken the approach and applied it to all Github projects we’re sourcing. We also provide the raw data as a means for users to “slice-and-dice” in ways they see fit or ways we haven’t thought of yet.

The sourcing and consolidation of the source data is wrapped by a build process written in Node.js that runs on Github Actions and collects new data on a daily basis. The data collection process itself is not wedded to a given data source. In our source repository we implemented the concept of “processors” that are tailored to a given source and then normalize the data to the registry format. As part of this process different tools are categorized using a Bayesian approach then attempts to put tools into the right “bucket”.

The repository as it stands is really just a first cut. There is more work to be done, with a list of issues currently focused on improving data quality, creating better categories and providing the data in a variety of formats. There is also an opportunity to use this data for outreach to tooling users, using it as an engagement tool to encourage them to both describe their needs and advance their tooling to the latest version of OpenAPI. There is also an opportunity to bring tooling data together across specification languages – GraphQL, Async API, JSON Schema et al – to elicit a more holistic view of the API ecosystem and look at how cross-specification tooling might be of benefit.
As always feedback is welcome. If you have any suggestions for improvement please raise them on the repository or get in touch if you’d like to talk in more detail about any aspect of the implementation.

Why the Largest Geospatial Organization in the World Uses the OpenAPI Specification

By Blog

The Open Geospatial Consortium (OGC) recently announced that OGC API – Tiles was adopted as an official OGC Standard. The OGC is a collective problem-solving community of experts from more than 500 businesses, government agencies, research organizations, and universities representing hundreds of thousands of geospatial professionals driven to make geospatial (location) information and services FAIR – Findable, Accessible, Interoperable, and Reusable.

The OGC API - Tiles Standard defines building blocks for creating Web APIs that support the retrieval of geospatial information as tiles. Different forms of geospatial information are supported, such as tiles of vector features (“vector tiles”), maps, imagery, and other types of geospatial information.

The new standard focuses on simple reusable REST API building blocks that can be described using the OpenAPI Specification.

Dr. Gobe Hobona, is the Director of Product Management, Standards at Open Geospatial Consortium (OGC). 

Dr. Hobona joined OGC Staff in 2017, having been an OGC member since 2004. As the Director of Product Management, he provides oversight of the development of OGC API Standards, managing releases, and product marketing.

Who uses the Open Geospatial Consortium and why? Can you give an example?

Standards by the Open Geospatial Consortium are used by hundreds of organizations to publish millions of datasets, as reported by GeoSeer.net. Many of the organizations are OGC Members that all actively participate in a consensus process that designs and publishes standard specifications which improve interoperability. A few of the domains that make use of OGC Standards are Aviation, Built Environment & 3D, Business Intelligence, Government & Spatial Data Infrastructure, Energy & Utilities, and many more. 

A great example of those standards being used would be in the aviation industry like EUROCONTROL, the European Air control agency and the Federal Aviation Administration (FAA) in the United States. Those teams publish a lot of their data using OGC Standards, specifically the Geography Markup Language (GML) which they have implemented in the Aeronautical Information Exchange Model (AIXM). Another example of the use of the standards is the OGC API – Features Standard which has been adopted as a Good Practice for implementing download services that are compliant with the European Union’s INSPIRE Directive, which positively affects hundreds of millions of EU citizens across the continent.

What’s new about the release of OGC API – Tiles? How will this be used? Who should use this?

We are really excited about it. The OGC API – Tiles Standard has been in the works for a number of years and now it is here. The OGC API defines building blocks for creating Web APIs that support the retrieval of geospatial information in tiles, basically little image chips that can be streamed with nearby chips to show a map. There are many great things about it, some special features include map tiles and vector tiles. Rather than the end user having to retrieve a large data set for the whole world, they can just retrieve that single tile. They can then use the identifier for that tile to collaborate with colleagues. Those in environmental sciences might retrieve a tile from other specialties and vice-versa. Now, instead of transferring terabytes of data across a network, it is just a subset. 

We have standardized models for Tile Matrices, we have a registry where various organizations can agree on a set of tiling schemes to use together. There have been significant efficiency and cost savings seen across the board. Transmitting complete datasets over a network can incur some charges, so transmitting only relevant subsets offers cost savings. Also, performance has improved. For tiles that do not change, it is now possible to provide a cached tile. We recently hosted a code sprint in Brussels where developers came together from across the globe, and within a short time they were able to implement this standard, and simply just used the implementations through various client applications. 

I’ll point out, all of that was made possible because the OGC API – Tiles Standard uses the OpenAPI Specification, which makes it attainable for web components to describe the capabilities for the resources, schemas, and so much more. In the previous generation of web service standards, it required developers to interpret the requirements of a standard. Now it is possible for some of that role to be done by the applications themselves. Apps can interpret what the API is intended to do. This takes away the burden from the developers and it leads to very happy developers!

What is the advantage of open source with spatial information?

Open standards by the OGC are used by both open source and proprietary software products; they do that to make Geospatial information more findable, accessible, interoperable, and reusable. One key thing about open standards and open source software is that they reduce the risk of vendor lock-in. With vendor lock-in, an organization gets tied to a single vendor and they must obtain products from that vendor. With open standards and open source software, it certainly reduces the risk of this and organizations do not have to buy from a single vendor. Furthermore, some common parts of commercial software come from open source to reduce the cost of developing some of that fundamental technology that can be shared; for example, the open source GDAL library is used by several commercial software products.

Why do you support the OpenAPI Specification? What are the main advantages?

The OpenAPI Specification makes it possible for developers to automatically create source code through code generators, by simply parsing an API definition document that complies with the OpenAPI Specification. In the past, most creation of source code required developers to manually read and interpret API definition documents, which led to human error and was certain to take longer to implement interfaces. Now, a lot of the interpretation is done by the application and then the human developer joins to codify the business logic. Moreover, using OpenAPI means that all of our APIs are defined in a consistent way so that the use of the APIs is predictable for all developers.

The efficiency gain for an organization is incredible. It is one of the key reasons why the OpenAPI Specification has been looked upon favorably by the OGC community.

OGC develops open standards, so everyone has the opportunity to provide some input to the standards. Other organizations do not have to wonder if there are some restrictions to access to the standards. But also, organizations can feed requirements in, as a community both the OGC and the Linux Foundation, which houses the OpenAPI Initiative and looks after the OpenAPI Specification, have done an excellent job of involving everyone across industry. There is a lot of feedback that is included or at least considered in the design of those standards. Everyone in the community has a chance to include input into those standards.

What is the best way to get involved in the OGC?

The OGC runs three member meetings a year, in different parts of the world, and with hundreds of participants. Now that travel restrictions are easing up, those meetings are now hybrid meetings with remote participants being supported. 

OGC working groups use those meetings to gather needs and specs. In between those meetings, there are a series of working group get-togethers. For anyone that is interested in participating, I would recommend going to the OGC website and have a look at the information about membership, there is also a list of working groups. We have domain working groups in defense, aviation, meteorology, and more. We also have other working groups that focus on specification, like OGC API – Tiles and OGC API – Features.  

The next OGC meeting will be from 20th to 24th February 2023, hosted by the European Space Agency in Frascati, Italy. That will be the first of three taking place in 2023, there will be another in June in Huntsville, Alabama, and another in September in Singapore.

I would also like to mention, the OGC runs several initiatives, we run innovation initiatives, where members can join in. These are run by the Collaborative Solutions and Innovations team in OGC, those initiatives are funded by the OGC membership, and they provide an opportunity for research and development. I encourage anyone interested to look at the OGC website and participate in these activities.

The OpenAPI Initiative (OAI) was created by a consortium of forward-looking industry experts who recognize the immense value of standardizing on how APIs are described. As an open governance structure under the Linux Foundation, the OAI is focused on creating, evolving and promoting a vendor neutral description format. The OpenAPI Specification was originally based on the Swagger Specification, donated by SmartBear Software. To get involved with the OpenAPI Initiative, please visit https://www.openapis.org

Bump.sh, API Contract Management Platform, Joins the OpenAPI Initiative

By Blog

The OpenAPI Initiative, the consortium of forward-looking industry experts focused on evolving and implementing the OpenAPI Specification (OAS), is announcing that Bump.sh has joined as a new member. Welcome!

Bump.sh is an API contract management platform that helps document and tracks APIs: identifying what changes in APIs structure, and keeping developers up to date across an organization. Bump.sh acts as a single source of truth with information that remains up to date and changelogs.

The company has raised $4 million in funding led by Galion.exe and Bpifrance’s Digital Venture fund. 

“We believe schemas are the cornerstone of future-proof API development. As a vendor, it is our duty to contribute to and keep up to date with the latest specifications,” said Sébastien Charrier, CEO of Bump.sh. “Joining the OpenAPI community will help us better support our customers and contribute to the direction of OpenAPI Specification development.”
