A NISO/DCMI Webinar with Makx Dekkers and Stijn Goedertier will be held online at 1:00PM Eastern Time on 30 October 2013 (17:00 UTC - see World Clock: http://bit.ly/19EvBJe). 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. Additional information can be found at http://www.niso.org/news/events/2013/dcmi/publicsector. Registration for the webinar closes 30 October 2013 at 12:00PM Eastern (16:00 UTC).
