Asset Description Metadata Schema (ADMS)


Metadata standard

When is this solution for you? 

You are involved in the metadata management of a European public administration or service and want to explore, (re-)use or share semantic assets (metadata or reference data).

You are looking for ways to:
- describe semantic assets in a common way so that they can be seamlessly cross-queried and discovered by ICT developers  from a single access point, such as Joinup;
- search, identify, retrieve, compare semantic assets to be reused avoiding duplication and expensive design work through a single point of access;
- keep own system for documenting and storing semantic assets;
- improve indexing and visibility of own assets;
- link semantic assets to one another in cross-border and cross-sector settings.

What can we offer you? 

The Asset Description Metadata Schema (ADMS) is a simple specification used to describe interoperability solutions helping everyone to search and discover them. ADMS allows:

  • Solution providers, such as standardisation organisations and public administrations, to describe their interoperability solutions using the standardised descriptive metadata terms of ADMS, while keeping their own system for documenting and storing them;
  • Content aggregators, such as Joinup, to aggregate such descriptions into a single point of access;
  • ICT developers to more easily explore, find, identify, select and obtain interoperability solutions from a single point of access.

Who is already using this solution? 
  • Joinup: This online platform provided by the European Commission hosts a collection of reusable interoperability solutions. It aims to help public administrations to offer modern, user-friendly and interoperable public services while reducing costs by reusing solutions which have already been developed. ADMS is used as the basis for organising and harmonising the descriptive metadata of these solutions.
  • Metadata Registry (MDR) of the EU Publications Office: ADMS-compliant RDF export for MDR Named Authority Lists. The registry registers and maintains the definition data (metadata elements, named authority lists, schemas, etc.). These are used by the different European Institutions involved in the legislative process and by the Publications Office of the EU in its production and dissemination process. 
  • ADMS-enabled description of a vocabulary implemented in PoolParty Thesaurus Manager 3.1.0: PoolParty Thesaurus Manager (PPT) allows the content architect to fill in the full description of a controlled vocabulary (a SKOS Thesaurus) following ADMS standards.
  • ADMS export feature for XRepository: The XRepository of the German Federal Ministry of the Interior supports the processes of development and distribution of standards.
