Supporting Ordering in schema.org

Schema.org Blog — 2026-06-17T17:54:40+00:00

Ordering is hard in RDF. Triples are not ordered by default and expressing order requires either relying on implicit syntax or RDF structures like rdf:List or rdf:Seq. We’re not going to fix that at schema.org but we do want to take some small steps to make it easier. Currently, it is unclear whether the individual […]

Announcing OpenWEMI

Dublin Core (DCMI) — 2024-08-02T00:00:00+00:00

In 1998, the International Federation of Library Associations introduced a new model for library catalog data, focusing on the bibliographic relationships within metadata. This model, known as the Library Reference Model (LRM), includes four main elements: Work, Expression, Manifestation, and Item (WEMI), each representing different aspects of created resources. To support the broader use of these WEMI concepts, OpenWEMI was developed by the Dublin Core Metadata Initiative, providing a general v

Dublin Core (DCMI) — 2024-06-30T00:00:00+00:00

Data is now the cornerstone of advanced research across various fields, including the humanities and social sciences. These disciplines increasingly rely on data, generating new information as evidence or demonstrating innovative practices. To combat research fraud and promote broader dissemination, publication venues now require data sharing. Recognizing the importance of open data environments, it’s crucial to provide scholars with easy access. Despite growing interest, efforts in data aggrega

NKOS Workshop on AI and KOS at DCMI-2024 in Toronto

An NKOS Workshop will be held at DCMI 2024, the twenty-fourth International Conference on Dublin Core and Metadata Applications, October 20-23, Toronto, Canada. The NKOS Workshop is particularly interested in how knowledge organization systems (KOS) are being used or can be used to make automation intelligent. For example, one problem with LLMs is “hallucinations” where the application generates a response to a prompt that is “correct” but not true. How can KOS be integrated with LLMs to guide t

Dublin Core announces openWEMI for community review

Dublin Core (DCMI) — 2023-11-29T00:00:00+00:00

Dublin Core introduces openWEMI for community review, a minimally constrained RDF vocabulary based on Work, Expression, Manifestation, and Item (WEMI) concepts. It diverges from IFLA's library-focused approach, offering broader application in metadata modeling and including the Endeavor class and common properties for diverse metadata resources. The vocabulary, with documentation and a turtle file, seeks feedback via GitHub and a mailing list.

JSON Feed version 1.1

JSON Feed — 2020-08-07T16:44:36+00:00

We’ve updated the spec to version 1.1. It’s a minor update to JSON Feed, clarifying a few things in the spec and adding a couple new fields such as authors and language.

For version 1.1, we’re starting to move to the more specific MIME type application/feed+json. Clients that parse HTML to discover feeds should prefer that MIME type, while still falling back to accepting application/json too.

The code page has also been updated with several new code libraries and apps that support JSON Feed.

COVID-19 schema for CDC hospital reporting

The COVID-19 pandemic requires various medical and government authorities to aggregate data about available resources from a wide range of medical facilities. Clearly standard schemas for this structured data can be very useful. The Centers for Disease Control (CDC) in the U.S. defined a set of data fields to facilitate exchange of this data. We are introducing a Schema.org […]

Announcing JSON Feed

JSON Feed — 2017-05-17T15:02:12+00:00

We — Manton Reece and Brent Simmons — have noticed that JSON has become the developers’ choice for APIs, and that developers will often go out of their way to avoid XML. JSON is simpler to read and write, and it’s less prone to bugs.

So we developed JSON Feed, a format similar to RSS and Atom but in JSON. It reflects the lessons learned from our years of work reading and publishing feeds.

See the spec. It’s at version 1, which may be the only version ever needed. If future versions are needed, version 1 feeds will still be valid feeds.

Notes

We have a WordPress plugin and, coming soon, a JSON Feed Parser for Swift. As more code is written, by us and others, we’ll update the code page.

See Mapping RSS and Atom to JSON Feed for more on the similarities between the formats.

This website — the Markdown files and supporting resources — is up on GitHub, and you’re welcome to comment there.

This website is also a blog, and you can subscribe to the RSS feed or the JSON feed (if your reader supports it).

We worked with a number of people on this over the course of several months. We list them, and thank them, at the bottom of the spec. But — most importantly — Craig Hockenberry spent a little time making it look pretty. :)

Yahoo Groups Dropped RSS Feed Support
