SDWIG: Spatial Data on the Web IG

The mission of the Spatial Data on the Web Interest Group is to develop and maintain vocabularies and best practices that encourage better sharing of spatial data on the Web; and identify areas where standards should be developed jointly by both W3C and the Open Geospatial Consortium (OGC).

DXWG: Dataset Exchange WG

The Dataset Exchange Working Group aims to extend the existing DCAT standard in line with wider practice but also to recognise and support diverse approaches to data description and Dataset Exchange more generally.

SDW: Spatial Data on the Web WG

The Spatial Data on the Web Working Group is a joint initiative of W3C and OGC, aiming at bridging the geospatial and Web platforms, and facilitating the publication and use of spatial data on the Web.

POWDER: Protocol for Web Description Resources

The POWDER Working Group aims at developing a mechanism through which structured metadata (“Description Resources”) can be authenticated and applied to groups of Web resources.

EU ISA Programme


The objective of the GeoDCAT-AP Working Group is to define an RDF syntax that can be used for the exchange of descriptions of spatial datasets among data portals. The RDF syntax should extend the DCAT Application Profile for data portals in Europe (DCAT-AP), to model metadata elements defined in the core profile of ISO 19115 and in the INSPIRE specifications.

DCAT-AP: DCAT Application Profile for European Data Portals

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 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 datasets among data portals.

CLV: Core Location Vocabulary

The Core Location Vocabulary is a simplified, reusable and extensible data model that captures the fundamental characteristics of a location, represented as an address, a geographic name, or a geometry.

ADMS: Asset Description Metadata Schema

The Asset Description Metadata Schema (ADMS) is a vocabulary to describe interoperability assets making it possible for ICT developers to explore and search for interoperability assets.

DELOS: Network of Excellence on Digital Libraries

The DELOS network intends to conduct a joint program of activities aimed at integrating and coordinating the ongoing research activities of the major European teams working in digital library (DL) related areas with the goal of developing the next generation DL technologies. The objective is to a) define unifying and comprehensive theories and frameworks over the life-cycle of DL information, and b) build interoperable multimodal/multilingual services and integrated content management ranging from the personal to the global for the special and the general population. The Network aims at developing generic DL technology to be incorporated into industrial-strength DL Management Systems, offering advanced functionality through reliable and extensible services.

DHX: Digital Ecological and Artistic Heritage Exchange

The project aims to establish a networked virtual reality infrastructure and content development environment for museums and cyber theatres, for mutual exchange of digital cultural and natural heritage. European and Asian partners are participating for transcontinental shared immersive experience in a global scale using high-bandwidth trans Euro-Asian networks.

QUATRO Plus: Content Labels for User Empowerment

This project starts from the results of the QUATRO project in order to build a more extended platform for Web quality assurance, based on the specifications released by the POWDER WG, and including social networking and collaborative rating of Web resources and content/quality labels released by third-parties.

QUATRO: Quality Assurance and Content Description

The project aims at providing a common platform for quality labels making it possible for the many existing labelling schemes to be brought together through a single, coherent approach without affecting an individual scheme's assessment criteria or independence. The platform will support i) easy, flexible routes for content providers to add quality labels to their sites that are both ‘visible’ to humans and machines, ii) automatic validation of quality labels against a label operator's database, and iii) real-time probabilistic label verification. As well, the proposed platform will have direct applicability to content descriptions, classification and so-called “discovery metadata.”

EUFORBIA: Experiments about the Filtering of Internet Documents according to an Unbiased and Semantic-rich Approach

This project aims to demonstrate the possibility of using an unbiased and semantic-rich approach for executing an accurate (rating and) filtering of Internet documents. The principal objective of this project is to contribute to the production and use of new generations of Internet filtering systems, more powerful and flexible than the existing ones, and easier to adapt to cultural, political or religious differences.
