How Can SiteSearch Help
• Look at product history
• Look at near term plans
• Hear your ideas
OCLC SiteSearch User Group Meeting - March 24, 1999
SiteSearch 1.0
•
•
•
•
One product
Batch database building
Z39.50 server
TTY Z39.50 client
– very limited customization
• FirstSearch at your library
OCLC SiteSearch User Group Meeting - March 24, 1999
SiteSearch 3.0
• Web-based Z39.50 client
– Proprietary HTTP server
– Proprietary customization
• Format Control Language
• WebZ Entity Language (Ralph)
• Obi as starter interface
• Same Z39.50 and Database Building
• Proprietary Imaging Support
OCLC SiteSearch User Group Meeting - March 24, 1999
SiteSearch 4.0
• Java based
• Standard HTTP and open architecture
• Enhanced Z39.50 architecture
– Virtual database capabilities
– Even for non Z39.50
• Same Database Building
OCLC SiteSearch User Group Meeting - March 24, 1999
SiteSearch 4.1 Emphasis
• Improve Database Building
– Creating Metadata
– Online Update

• Indexing support for loosely structured text
like EAD
OCLC SiteSearch User Group Meeting - March 24, 1999
Easier to Use Than Newton
• Fewer Files
• Files Grow Automatically
• Fewer Programs
OCLC SiteSearch User Group Meeting - March 24, 1999
Automatic File Growth

OCLC SiteSearch User Group Meeting - March 24, 1999
More Reliability
• Java environment catches many errors
• Methods throw exceptions which must be
handled somewhere
• Updates fail safely
OCLC SiteSearch User Group Meeting - March 24, 1999
New File Architecture Lets
Updates Fail Safely
• Changes to the database are written to a
separate file and not committed until all
changes have completed successfully.
• Changes at the end of the file are committed
first.
