Resource Location and Archive Management

File & Document Naming Resource Discovery

Overall Status

Prototype from January ‘95 Implementation for Production

Version

Archive Management: Background

Archive Management Requires File Mobility

On-line Access Requires File Stability

Result: URNs = Permanent Names w/ Lookup service

Archive Management: Status

Prototype URN Resolver via CGI script

“Official” Syntax is being developed under IETF

Bibcodes (re: CDS, ADS) are adequate for now

Resource Location: Background

3 Methods of Access - Search, Browse, Direct (bibliographic)

Direct Access requires knowledge of URN

Require a query service to discover URNs/URLs

Resource Location: Status

Citation Records of Bibliographic Information - URC.0

Generated automatically at ingest time

SGML-like tags provide full-text and field-based searching using Isite

The result of a search is a “card catalog entry”, including URNs & URLs

Next Steps

EApJ and ADS already link to each other at URN level

Implement URN resolver & URC query service for EApJ

Interoperability development needed to link URC query systems
