TAO: Transitioning Applications to Ontologies

  • Completed
  • Programme: FP6
  • Call: IST-2004-2.4.7 - Semantic-based Knowledge and Content Systems
  • Start date: 01.03.2006
  • End date: 28.02.2009

TAO (Transitioning Applications to Ontologies) is about how existing ‘legacy’ applications can migrate to open, semantics-based Service-Oriented Architectures (SOA). Semantic Web Services (SWS), and SOA that host them will make a significant contribution to the competitiveness of European ICT in the coming period.

This will happen in two ways. First, Enterprise Applications Integration (EAI) will become less costly and more reliable because of explicit modeling of the meaning of data and processes in the systems owned by different business units. Second, B2B and B2C eCommerce systems will become:

  • More reusable, with interfaces that are meaningful for machines as well as for humans
  • More dynamic and adaptive, with the possibility of virtual applications composed of dynamically discovered components
  • More scalable, distributed across multiple machines
  • Sellable as discrete elements in the application service providers market

TAO is funded as a Specific Targeted Research Project under European Commission 6th FP with a budget around 3M euros. It started March 2006 and runs for 3 years. TAO is coordinated by University of Sheffield, UK.

Project Overview

The project’s main goal is to define a low-cost route to transitioning legacy systems to the open semantic SOAs, which will enable semantic interoperability between heterogeneous data resources and distributed applications. This low-cost migration path will be accessible to both SMEs (which are cost sensitive) and large enterprises (with huge investments in complex and critical IS).
The three RTD objectives of TAO are:

  • SWS bootstrapping via a semi-automatic acquisition of domain ontologies from legacy DB schemata, application documentation, and API-level code and comments
  • Augmentation and integration of legacy content (databases and documents used by applications) relative to the domain ontologies to create semantic repositories with ontology-based information access
  • Transitioning Methodology and Infrastructure: support the developer with a user-friendly infrastructure for the transitioning of existing application into semantic SOAs. An SWS bootstrapping methodology with detailed examples from an open-source reference application will be provided to facilitate take-up
