Our testing ground:

PhysDoc: Physics Documents Link collection of Documents on distributed database

Physics Institutions Servers

Search facility for documents service provider

allowing qualified queries

using Metadata (DC) in html documents / shadow files also still: extractors try to structure documents from layout

Using XML for encoding Metadata in distributed systems (PhysDoc)

Documents stay with the Authors

Need for easy to use tools for document upload for qualifying documents for guaranteeing consistency (theses)



Need for easy to use tools for document upload Upload for qualifying documents Metadata for guaranteeing consistency (theses) DigSig

Metadata Encoding structure browsable robot read

html 2.0 <meta> flat yes some

html 4.0 <meta> little yes no

XML <RDF> high to be done to be done

xhtml: well...

MetaMaker, one among many:

CURD: CARMEN UPLOADER WITH RDF AND DIGSIG GENERATOR

Generates RDF for Document description

containing DC, vCard, OAMS

Generates DigSig for all or parts

Generates URN (if possible)

Generates html for human reading description

Can manage upload process

CURD is Part of the CARMEN Projecthttp://www.mathematik.uni-osnabrueck.de/projects/carmen/

CARMEN is part of the Global Info project of the German Ministry for Education and Research BMBF.


One Example for Encoding of Document Despription:


<rdf:RDF xmlns:rdf = "http://www.w3c.org/1999/02/22-rdf-synax-ns#" xmlns:dc = "http://purl.org/dc/elements/1.0/#" xmlns:vcard = "http://imc.org/vCard/3.0#" xmlns:oams ="http://www.openarchives.org/sfc/sfc_oams.htm#"> <rdf:Description> <rdf:Description xml:lang="en" rdf:about="http://xxx.lanl.gov/abs/cond-mat/9909184"> <dc:Title> <rdf:alt> <rdf:li xml:lang="en"> Classification of phase transitions in small systems </rdf:li>...

Metadata:


DC OAMS

vCard

URN

Still no Schema for description of authors rights(was idea of dc.rights)

OAMS can be generated form DC and vCard automatically,if the Semantics do match.
