OCLC SiteSearch 4.1 OverviewBecky Babyak
8
OCLC SiteSearch 4.1 Highlights
  • Integrate Information Resources
  • New Merged Results and De-duplication
  • Access that meets user needs
  • New Vocabulary Assisted Searching
  • Build local information resources
  • New Record Builder component
  • Available July 1999

9
OCLC SiteSearch WebZ Enhancements
  • Merged Result Sets
  • Duplicate Record Detection
  • Vocabulary Assisted Searching
  • Enhanced remote Z39.50 access
  • - Configuration for all six bib-1 attribute types
  • - Query customized for the target database

10
Merged Result Sets
  • Modified cross database record navigation
  • Sorts merge records from all databases
  • Database name displayed in record

11
Duplicate Record Detection
  • Z39.50 Duplicate Detection Service
  • Duplicate records are available for display
  • Defined at the database level
  • System Administrator can configure
  • Fields in the record which make up the dedup key
  • Dedup threshold (maximum number of records)
  • Must have merged result sets for dedup

12
Vocabulary Assisted Searching
  • Helps end users
  • Find subject terms related to their query
  • Determine the best terms for their query
  • Provides thesaurus support when available
  • Target database has associated thesaurus
  • Results in approved terms from thesaurus entries
  • Related term list when no thesaurus

13
OCLC SiteSearch Database Builder Enhancements
  • Batch online update
  • Users can search database
  • while its being updated
  • New Record Builder component

14
OCLC SiteSearch Record Builder Component
  • Build local information resources
  • Create metadata records via the Web
  • Add records to a database in real time
  • Edit and modify records
  • Links to external digital objects
  • Current database builder licensees receive as an
    update

17
Libraries and Information Access
  • Know information
  • Know their patrons
  • Know how their patrons use information
  • Best suited to be information gateways
  • Best suited to organize local information
  • Cant do it all alone

18
How Can SiteSearch Help
  • Look at product history
  • Look at near term plans
  • Hear your ideas

19
SiteSearch 1.0
  • One product
  • Batch database building
  • Z39.50 server
  • TTY Z39.50 client
  • very limited customization
  • FirstSearch at your library

20
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

21
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

22
SiteSearch 4.1 Emphasis
  • Improve Database Building
  • Creating Metadata
  • Online Update
  • RDF and XML framework
  • open architecture
  • Continued enhancements to WebZ

23
Next Pears -- Better Databases
  • Simpler databases -- 1 database file
  • Java-based Database Build Utilities
  • Open architecture
  • Customized normalization and indexing
  • Unicode
  • Indexing support for loosely structured text like
    EAD

24
Easier to Use Than Newton
  • Fewer Files
  • Files Grow Automatically
  • Fewer Programs

25
Automatic File Growth
  • Newton files are preconfigured for size. (IBM
    Mainframe file model)
  • Pears databases grow automatically. (Standard
    UNIX file model)

26
Five Files Become One

28
More Functionality
  • Unicode
  • User Customizable Indexing
  • Relevance Ranking
  • Online Update
  • Embeddability

29
More Reliability
  • Java environment catches many errors
  • Methods throw exceptions which must be handled
    somewhere
  • Updates fail safely

30
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.

31
Enhancements over Newton
  • Unlimited Number of Indexes
  • Index Nodes Binary-Searchable
  • Short Postings Lists in Index
  • Postings List Maps arbitrarily large
  • Variable Length Integers

32
Conversion Programs Gone!
  • Use RecordHandlers Instead!
  • Can already read USMARC, SGML/XML, BER, .DB and
    .PDB
  • Support user defined filters
  • RecordHandler class still usable as conversion
    program

33
DBDESC Language Gone!
  • Use dbdesc.ini Instead!
  • DB
  • blocksize16384
  • InputRecordTypeSGML
  • Nameddc21
  • RecordHandler
  • TagsFileddc21.tags

Breakout Session Feedback from You
36
Formatting Classes Group
  • More Documentation/instructions/ JavaDoc for
    formatting classes
  • Formatting classes with simpler setup
  • Quick easy classes that fully implement MARC
  • FCL-like tool
  • Optimize response time
  • Will .ini files affect this

37
Non-Z39.50 Access Group
  • Web-based configuration and admin
  • Add Obi Topics to user profile
  • Define Record structure outside formatting
    classes
  • i.e., Formatting configuration files

38
Access Component Group
  • Better documentation
  • General solutions that work across vendors
  • Enhanced Access Servers

39
Interface Design Group
  • Better reference materials (object interaction
    diagrams)
  • Examples of other users implementations
  • Ability to export citations into local citation
    management software (e.g., Endnote, ProCite)

40
Database Builder Group
  • Friendly dynamic updates for 4.1
  • Formatting for databases defined in the
    configuration files
  • Web interface to the configuration files
  • Endnote to query SiteSearch

41
Resource Sharing Group
  • Easy Authentication
  • Opportunities for shared discussion
  • Models that work
  • Archive for sharing opportunities
  • How tos in the documentation
