Metadata is Dead, Long Live the New Data RA-EKI: a Use Case on Knowledge Management for the IT Realm

Daniel Fitzpatrick, François Coallier and Sylvie Ratté


IT business is business like any other business. This research, in progress, does not eliminate the need of the data and information traditionally called metadata. It does not undermine the advances in multimedia document standards such as XMP, MPEG-7 and Dublin Core. This research considers this domain data equally important to all of the other business data. As in the financial and human domains, IT resources serve the enterprise as strategic assets. As such, IT concepts belong to the corporate semantic pool, along with concepts of other business domains, which constitute the enterprise ontology structure. The authors propose the Reference Architecture of an Enterprise Knowledge Infrastructure (RA-EKI) for end-to-end knowledge lifecycle management. RA-EKI, illustrated below, comprises a set of ontology-based applications. RA-EKI's applications transform unstructured and semi-structured data into structured data. They then integrate the data from heterogeneous sources and transform the data into information (contextualized data) in the form of dashboards and data marts. At the end of the cycle, RA-EKI's applications extract knowledge (actionable information). Knowledge is then reused and circulated through the enterprise ontologies. This paper describes related work, diverse and relatively unfocused, covering data, information and application description to technology infrastructure and SOA services. It provide a definition of metadata as found in the literature that would be thereon considered as data of the IT realm. The paper then provides an oversight of RA-EKI, illustrating the complete set of transformations from unstructured data to knowledge. The paper comprises a use case exemplifying RA-EKI's potential contributions with a holistic perspective on the IT realm.
