Live Integration Framework




   The Problem

       ●   Increasing amount of information

       ●   Information stored in various heterogeneous data stores

       ●   Redundancy

       ●   Retrieve all information about a specific subject often difficult




   topicmapslab.de
Live Integration Framework




   Why Topic Maps?

       ●   Not exactly a new idea

       ●   Subject centric presentation

       ●   Merging of different data sources

       ●   Adding additional semantic information




   topicmapslab.de
Live Integration Framework




   Our Goal

       ●   Support various storage technologies

       ●   “Never touch a running system”

       ●   Full read access

       ●   “Live” view on the data




   topicmapslab.de
Live Integration Framework




   Requirements

       ●   Structured data

       ●   Subjects need identities → Problem

                                 ●   Technology specific implementation
                                     and mapping definition

   Current State

       ●   Work in progress

       ●   Implementation only for RDBMS so far

       ●   Only MySQL

       ●   Still some features to implement




   topicmapslab.de
Live Integration Framework




   Current State

       ●   Topics from single tables

       ●   Unique key required

       ●   Attributes to characteristics and Identifier

       ●   Specify queries in mapping

       ●   Associations from any combination of keys

       ●   Specify types, scopes and datatypes

       ●   Association reifier




   topicmapslab.de
Live Integration Framework




   Future Work

       ●   Support other storage technologies

       ●   Improve mapping for RDBMS

       ●   Support different RDBMS types (Postgres, Oracle, etc.)

       ●   Allow limited write access

       ●   Support temporary caching
