Subject: RE: [regrep] Presentations and questions : taxonomy vs. classification
* How to register namespaces? On this item, there was interest and discussion with Boeing (believe Erik Still) and NIST. I believe they were discussing URIs that point to a resource file that is like metadata for a namespace. This may overlap this question and the other ones associated with a URI (which may be a broader question that the RegistryObject and the HTTP capabilities discussed to this point). I think we have multiple questions here.

More detail on his question follows: 1. Comparison between the two concepts ebXML Reg/Rep with OAIS [Reference Model for an Open Archival Information System (OAIS)] 2. Capability to ensure integrity of objects over time 3. If a checksum may be required to ensure that the object is what was submitted over time (mentioned by Lane in discussion). Please respond with answers on the third question (details 1-3 above) directly to the list and Derek Lane at lane.derek@epa.gov The link to OAIS is at: http://ssdoo.gsfc.nasa.gov/nost/isoas/overview.html Please also feel free to discuss each of the other questions above on the list. This is a good opportunity to address some of these questions, and possibly consider for version 4.0 or as topics of best practice papers! -----Original Message----- From: Farrukh Najmi [mailto:farrukh.najmi@sun.com] Sent: Tuesday, January 28, 2003 12:52 PM To: Berry, Nicholas F Cc: Chiusano Joseph; ebXML Regrep (E-mail); sang.shin@sun.com; weida@apelon.com; akotok@disa.org; lane.derek@epa.gov Subject: Re: [regrep] Presentations and questions : taxonomy vs. classification In my experience: Taxonomy and Ontology are different levels of sophistication along the ontology continuum as defined by Deborak McGuiness in her paper. WIll post link when I find it. Classification on the other hand is the use of taxonomy/ontology to classify things. So taxonomy / ontology / classification schemes / topic maps etc. are nouns while an act of Classification is a verb involving some subject and the taxonomy. Similarly an instance of a Classification is like an adjective that decsribes a subject.

Ontologies represent a conceptual consensus of topics (concepts) and their related attributes within a community of interest (domain). They are based upon Formal Logic.
