How to make Enterprise Architecture Repositories work together? By implementing ADMS

In TOGAF and other Enterprise Architecture Frameworks, the Architecture Repository [1] is a holding area for reusable architectural work products [2] within the enterprise. Amongst others, it holds reusable outputs of projects and the standards with which information systems must comply.

The Architecture Repository supports governance processes and facilitates reuse across the enterprise. Many organisations face the challenge of how to centralise all reusable architectural work products in a single repository. This is not an easy task, particularly in medium- and large-sized organisations with several Content Management Systems, Wikis and other Web-based systems. In this case, syndication of architectural work products is a more efficient method than replicating work products in a central repository. Through the use of syndication [3] technology, information about the work products stored in different systems can become findable on a centralised repository. Internet Content Syndication [4] provides a solution to the vast size and rapid expansion of the Internet, while syndication of architectural work provides a solution to the existence of more than one content management system within the enterprise. For this approach to work each system holding architectural work products should publish descriptions about these products (such as their name, domain, their link, etc.) using a standardised vocabulary. These descriptions can then be made available on the central repository while the architectural work products remain on the originating system. The Asset Description Metadata Schema (ADMS) is a response to this challenge.

ADMS, standardised vocabulary created by the EU's ISA Programme [5] of the European Commission, helps organisations to describe standards as well as other architectural work products. ADMS provides the means for:

+ Syndicated architectural work products;

+ Coexistence of several Enterprise Architecture Repositories while keeping a centralised one which aggregates information about all architectural work products within the enterprise;

+ Better managed architectural work products.

ADMS version 1.00 [6] was released on 19 April 2012 under the ISA Open Metadata Licence v1.1 [7]. The ADMS specification is available to download in UML, XML, and RDF formats. Several Organisations have already started to implement ADMS and the specification will be maintained by W3C’s Government Linked Data (GLD) [8]. On 23 April, ADMS was presented at The Open Group Conference in Cannes [9] as part of the Semantic Interoperability track. The slides are available for download on Joinup [10]. The following day a broader discussion about semantic interoperability was held between The Open Group’s UDEF team and ISA’s team. More information about this meeting, including its conclusions, is available on The Open Group’s website [11].
