From the about page:

The CIARD Routemap to Information Nodes and Gateways (RING) is a project implemented within the Coherence in Information for Agricultural Research for Development (CIARD) initiative and is led by the Global Forum on Agricultural Research (GFAR).

The RING is a global directory of web-based information services and datasets for agricultural research for development (ARD). It is the principal tool created through the CIARD initiative to allow information providers to register their services and datasets in various categories and so facilitate the discovery of sources of agriculture-related information across the world.

The RING aims to provide an infrastructure to improve the accessibility of the outputs of agricultural research and of information relevant to ARD management.

The registry of resources is being leveraged to provide more advanced services, based on the Data Catalogue Vocabulary (DCAT).

Agriculture is an ongoing and vital activity. No shortage of data to be collected, reconciled and repackaged as an information product.

I first saw this in a tweet by Stefano Bertolo.

Implementations of Data Catalog Vocabulary

From the post:

The Government Linked Data (GLD) Working Group today published the Data Catalog Vocabulary (DCAT) as a Candidate Recommendation. DCAT allows governmental and non-governmental data catalogs to publish their entries in a standard machine-readable format so they can be managed, aggregated, and presented in other catalogs.

Originally developed at DERI, DCAT has evolved with input from a variety of stakeholders and is now stable and ready for widespread use. If you have a collection of data sources, please consider publishing DCAT metadata for it, and if you run a data catalog or portal, please consider making use of DCAT metadata you find. The Working Group is eager to receive comments reports of use at and is maintaining an Implementation Report.

If you know anyone in the United States government, please suggest this to them.

The more time the U.S. government spends on innocuous data, the less time it has to spy on its citizens and the citizens and governments of other countries.

I say innocuous data because I have yet to see any government release information that would discredit the current regime.

Wasn’t true for the Pentagon Papers, the Watergate tapes or the Snowden releases.

Can you think of any voluntary release of data by any government that discredited a current regime?

The reason for secrecy isn’t to protect techniques or sources.

Guess whose incompetence would be exposed by transparency?

DCAT Application Profile for Data Portals in Europe – Final Draft

DCAT Application Profile for Data Portals in Europe – Final Draft

From the post:

The DCAT Application profile for data portals in Europe (DCAT-AP) is a specification based on the Data Catalogue vocabulary (DCAT) for describing public sector datasets in Europe. Its basic use case is to enable a cross-data portal search for data sets and make public sector data better searchable across borders and sectors. This can be achieved by the exchange of descriptions of data sets among data portals.

This final draft is open for public review until 10 June 2013. Members of the public are invited to download the specification and post their comments directly on this page. To be able to do so you need to be registered and logged in.

If you are interested in integration of data from European data portals, it is worth the time to register, etc.

Not all the data you are going to need to integrate a data set but at least a start in the right direction.

Data Catalog Vocabulary (DCAT)


DCAT is an RDF vocabulary designed to facilitate interoperability between data catalogs published on the Web. This document defines the schema and provides examples for its use.

By using DCAT to describe datasets in data catalogs, publishers increase discoverability and enable applications easily to consume metadata from multiple catalogs. It further enables decentralized publishing of catalogs and facilitates federated dataset search across sites. Aggregated DCAT metadata can serve as a manifest file to facilitate digital preservation.

If you have comments, now would be a good time to finish them up for submission.

Socrata Open Data Server, Community Edition by Saf Rabah.

From the post:

Socrata, the leading provider of cloud-based open data systems, today announced the “Socrata Open Data Server, Community Edition,” to be offered as an open source reference implementation for open data standards. Designed expressly to promote data portability throughout the open data ecosystem, and support open source software policies in public organizations around the globe, the “Socrata Open Data Server, Community Edition” will be released in the first quarter of 2013, as freely downloadable open source software and fully integrated with other components of the company’s commercial software products.

To learn more about the proposed open data standards, or to get involved in this community effort, please visit

Looking forward to the release!

Resources on open data and various standards efforts related to the same.

Even with extensions, DCAT (Data Catalog Vocabulary) is going to leave a lot of room for mapping semantics between data sets.
