What is Asset Locator
A low cost, low maintenance, extensible, scaleable solution for
H
management
of software assets in the enterprise
Automatically
discovers and analyzes software assets
R
Provides
developers with tools/services in the following areas
L
Reuse, collaboration, impact analysis
Facilitates reuse via the following services
Semantic search engine
Navigation taxonomies (e.g. project topology, category, dependency)
Designed as an open framework
Customers and third party vendors can plugin additional functionality using
Asset Locator SDK

Extensible Framework
Provides extension points that enable customers and third party
H
vendors
to extend and configure its functionality
R Extension points are implemented via configuration setting and published
APIs
L Analyzers, crawlers, repository analysis, search service, result formatting,
client integration
The framework design proved effective and enabled Asset Locator
to be successfully integrated in several IBM products/offering
Shipped with VA TeamConnection v3.0.3, GA Sep 99
Used by IBM DeveloperWorks site to crawl/search for IBM RedBook
content

Using Asset Locator for Reuse
Repository exploration
HFinding potential reuse candidates
R
L
Semantic search service
Repository navigation views
Reference and hierarchy graphs
Categorization
Resource inspection
Much complex than inspecting documents in search engines
Examining reuse candidates via a set of inspection views
Resource integration / adaptation
Incorporate the assets for new purposes
Download, import and edit within the IDE
copyright (C) 2002, IBM Haifa Research Lab
Semantic Search Service
Free text search engine style queries (keywords, phrases,
linguistic
processing, ...)
H
Across the entire repository
R
Search
using language semantic constraints
L Increases precision when knowing what to search for
Combine free text and semantic based queries with boolean logic
(AND, OR, NOT)
Search for Java resources that "connects to a database" and extends
"HttpServlet"
Rank results according to relevance to search term
DB2 Text Extender is used to provide information retrieval functions
Inspect results using specialized details and navigational views

Summary
Asset Locator is a first attempt towards achieving ESAM
HComplements/extends existing processes and conventional reuse
R
Win-Win
solution
L Low investment/maintenance cost
Doesn't require change to organizational processes
No overhead for users
Global point of view
Lays the technology foundations for building customized tools
