  16. ISIM’06, Přerov 26.4.06; Corporate Memory ONTO Client • Needs: • Common formalized version of offers • Reasoning, inference • Common offers presentation • Operations (example) • Insert() – inserts OWL models in XML/RDF format into Onto CM • getXML() – returns plain XML of resource from Onto CM • executeRDQLQuery()- returns RDF ID result list for given RDQL query

  17. ISIM’06, Přerov 26.4.06; Corporate Memory Files Client • Needs: • Access to acquired original data files • Access plaintext form of original data • Store textual output of tools • Operations (example): • insert files to CM (as data stream / from uri) • deliver file (as stream / request URI) • list, cp, mv, delete

  18. ISIM’06, Přerov 26.4.06; Corporate Memory db client • Needs: • Store indices of content of documents and offers • Provide fast full-text search • Provide functionality for textual mining tools • Operations: • execute sql queries • enable definition of query templates • execution of stored procedures • update/insert/delete statements and templates
