Metadata play a primary position in either DLs and SDIs. in general outlined as "structured info approximately information" or "data which describe attributes of a source" or, extra easily, "information approximately data", it truly is a vital requirement for finding and comparing to be had facts. hence, this booklet specializes in the learn of alternative metadata facets, which give a contribution to a extra effective use of DLs and SDIs. the 3 major matters addressed are: the administration of nested collections of assets, the interoperability among metadata schemas, and the mixing of data retrieval ideas to the invention providers of geographic info catalogs (contributing during this technique to stay away from metadata content material heterogeneity)

The computation of the subsumption relation (by means of ﬁrst-order logic proof methods) allows the automatic construction of a classiﬁcation hierarchy, with conceptual deﬁnitions being arranged from the general to the speciﬁc. This automatic classiﬁcation is precisely the advantage with respect to frame-based languages, where classiﬁcation must be explicitly given by the designer of the knowledge base. , 1989). • Knowledge Interchange Format (KIF) (Genesereth and Fikes, 1992) and its successor Common Logic (CL) (Common Logic Working Group, 2004).
Ontologies have been developed in Artiﬁcial Intelligence to facilitate knowledge sharing and reuse. As it is mentioned in (Denny, 2002), the current heir to the artiﬁcial intelligence legacy may well be ontologies.
