  • 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. 
    ADMS allows public administrations, businesses, standardisation bodies and academia 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 their own system for documenting and storing semantic assets;
    improve indexing and visibility of their own assets;
    link semantic assets to one another in cross-border and cross-sector settings.

    14. 14. Terminology • Semantic interoperability: the ability of information and communication technology (ICT) systems and the business processes they support to exchange data and to enable the sharing of information and knowledge: Semantic Interoperability enables systems to combine received information with other information resources and to process it in a meaningful manner (European Interoperability Framework 2.0). It aims at the mental representations that human beings have of the meaning of any given data. • Semantic interoperability asset: highly reusable metadata (e.g. xml schemata, generic data models) and reference data (e.g. code lists, taxonomies, dictionaries, vocabularies) which are used for eGovernment system development.
    15. 15. ADMS Working Group: charter The ADMS Working Group was established in October 2011 to develop the Asset Description Metadata Schema (ADMS), a vocabulary to describe interoperability assets to make it possible for ICT developers to explore and search for interoperability assets. The objective of ADMS was 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, the collaborative portal of the European Commission’s ISA programme; • search, identify, retrieve and compare semantic assets to be reused, thereby avoiding duplication and expensive design work; • keep existing system for documenting and storing semantic assets; • improve indexing and visibility of assets; • link semantic assets to one another in cross-border and cross-sector settings.

    17. 17. Development approach • Building on earlier (unfinished) work that was done in 2010 and early 2011 • Targeting both XML and RDF environments – intended to provide a technology-neutral description • Using development methodology adapted from W3C methodology
    18. 18. Process and methodology • Process involving the widest range of stakeholders and domain experts with the aim to achieve consensus on a vocabulary for interoperability • Methodology for specification, including: – To define clearly the problem that the vocabulary will solve; – To make the overall structure of the vocabulary clear, indicating how existing vocabulary terms, and any new ones, work together; – To follow technical necessity and gain credibility, by following community convention when naming new terms; – To follow best practice when publishing the vocabulary. • https://joinup.ec.europa.eu/node/43160
    19. 19. Participant profiles • Official representatives of 15 EU Member States, several EU institutions and international organisations • External experts from 27 countries, including US and Australia • Government agencies, standards bodies, academia, research institutes, private sector
    20. 20. Use case • Enable e-Government system developers – to explore the semantic assets that are available in a particular subject area and to explore the relationships between semantic assets; – to find semantic assets that correspond to the user's stated search criteria; – to identify a semantic asset; – to select a semantic asset that is appropriate to the user's needs; – to obtain access to the semantic asset described.
    21. 21. Requirements • In order to support the aggregation of metadata for federated search, ADMS must specify: – The minimal subset (the ADMS Core) of metadata that must be exposed to federation partners and that are needed for the most frequent search cases; – A subset of recommended metadata extensions; – How to deal with multilingual properties; – How to expose or exchange the metadata.

    29. 29. Controlled vocabularies The ADMS specification defines a number of controlled vocabularies, e.g.: ADMS recommends the use of existing subject vocabularies, e.g. the European Commission’s ECLAS Thesaurus, EuroVoc, GEMET, AGROVOC, ZBW’s STW Thesaurus for Economics , the Library of Congress’ Subject Headings (LCSH) and Thesaurus for Graphic Materials (TGM). https://joinup.ec.europa.eu/svn/adms/ADMS_v1.00/ADMS_SKOS_v1.00.html
    30. 30. Conformance
    31. 31. Benefits The use of ADMS to describe interoperability assets (code lists, vocabularies, metadata schemas, specifications) enables: • Sharing descriptions of those assets • Aggregating descriptions in portals and catalogues • Better visibility and re-use leading to better interoperability across collections
    32. 32. ADMS is a W3C Working Group Note http://www.w3.org/TR/vocab-adms/
    33. 33. Relationship with standards • ADMS re-uses terms from several existing metadata standards: – DCAT: keyword, landingPage (of adms:Asset), accessURL, downloadURL (of adms:AssetDistribution) – Dublin Core: title, description, publisher, issued etc. – FOAF: name (of foaf:Agent) – SKOS: altLabel (of Asset) – Schema.org: startDate, endDate (of dct:PeriodOfTime) – … and OWL, VCard, POWDER, XHTML • It is in effect an Application Profile of Dublin Core as defined by DCMI
    34. 34. ADMS and DCAT • ADMS is also a profile of DCAT • DCAT is an RDF vocabulary designed to facilitate interoperability between data catalogs published on the Web. • A DCAT profile is a specification for data catalogs that adds additional constraints to DCAT. A data catalog that conforms to the profile also conforms to DCAT. Additional constraints in a profile may include: – A minimum set of required metadata fields – Classes and properties for additional metadata fields not covered in DCAT – Controlled vocabularies or URI sets as acceptable values for properties – Requirements for specific access mechanisms (RDF syntaxes, protocols) to the catalog's RDF description
    35. 35. ADMS and ISO/IEC 11179 – Metadata Registries ADMS is a metadata vocabulary to describe interoperability assets (data models and reference data) ISO/IEC 11179 addresses the semantics of data, the representation of data, and the registration of the descriptions of that data. It puts the focus on harmonising individual data elements contained within data models and reference data… http://www.iso.org/iso/home/store/catalogue_tc/catalogue_detail.htm?csnumber=35343

    49. 49. About the webinar One key challenge for e-Government programs around the world has been the lack of easily accessible information about the metadata schemas, controlled vocabularies, code lists, and other reference data that provide interoperability among a broad diversity of data sources. The Asset Description Metadata Schema was developed for exchanging information about such "interoperability assets". The schema was developed with support from the European Commission with the objective of facilitating interoperability across eGovernment programmes in Europe, but it is already proving its usefulness in a wider context, for example to describe specifications maintained by DCMI and W3C. One key implementation of ADMS is in a federation of semantic asset repositories on the Joinup server. Libraries that collect government information will benefit if such information is based on a set of commonly used schemas, vocabularies and code lists, making it easier to aggregate information from multiple sources. This webinar introduces the ADMS schema and discusses examples of its implementation.
    50. 50. About the speakers Makx Dekkers has been the editor in the development and consensus process for ADMS. He is an independent information professional who has been working in areas of information management, metadata and interoperability for more than three decades. After a career start in library and information networking and international cooperation, he became the Managing Director at DCMI in 2001, a position he held until 2011. Since then, he has been involved with projects concerning interoperability in the areas of Open Government Data and Public Sector information. makx@makxdekkers.com Stijn Goedertier has been working since 2010 as a contractor for the Interoperability Solutions for European Public Administration (ISA) Programme of the European Commission. His interests include digital public services, administrative processes, and semantic interoperability. Since 2011, he has been closely involved in the development and promotion of the e-Government Core Vocabularies and Asset Description Metadata Schema (ADMS) together with public administrations and standardisation organisations in Europe. In that context, Stijn was also responsible for the design and operation of the federation of semantic asset repositories on Joinup. Stijn is also a manager at PwC Technology Consulting where he focuses on Information Management. He has a Master degree in Business Engineering and a PhD in Process Mining. stijn.goedertier@pwc.be
