Outline

Discussion of Tom provided Pseudocodes -Proposed pseudo code is ok - We agreed on SKOS API which will be implemented in Java technology (by using Protégé DB for input and SKOS API for output) so that it can be extended in future and also use it as generic purpose. - URIs of XLabels are generated from Agrovoc Termcodes - Random URIs will be generated for adding new concepts/terms, as usual - Polysemyc labels: we all agreed on using straightforward SKOS aproach: each different meaning of a same linguistic expression will have separate XLabels

Export functionalities from WB

- Export format available: SKOS and SQL- User can choose the particular concept and export the information about that concept.- Allows export of

1. complete model (online it is impractical)2. selected concept (useful for web services and

linked data)3. selected concept with its children (undergoing)

- SKOS output is the hard coded outputted string of SKOS vocabularies (without any use of standard APIs). - SKOS-XL can also be provided as output export using the same above mechanism

Webservices

-- Web Services are generated from Protégé DB and Administrative DB.- Output format is SKOS and Text.- These Web Services are hard coded outputted string of SKOS/SKOS-XL vocabularies (without any use of standard APIs). - SKOS standards, 2005

Action Plan

SKOS API - To generate SKOS API from Tom Pseudocodes with wrapper so that Sesame, Allograph and other technologies can be integrated. - Sesame will be used for small portion of Agrovoc during initial development (faster development) - Allegrograph will be put in place silently at almost no integration effort (and totally no changes in the client code) for releasing the final v2.0 - Armando will send a small guideline of owlART (including maven database information) for learning and testing purpose of future SKOS API

-SKOS API will be gradually integrated with WB in a modular way which will differentiate of data layer and application layer.

Web Services and Linkdata - SKOS-XL will be integrated in the current WS for testing purpose by using current string based codes. Armando and Ahsan will provide WS specifications and examples to developers. - Old codes of WS will be thrown out after owl to SKOS conversion. - Need to redirect of URI from Aims to MIMOS server. Ahsan and Valeria will work on this issue.

• Proposed architecture of Agrovoc will be develop upon SOA architecture.• Business Logic layer and Data access layer will be extract out from Agrovoc WB and become a standalone web service.• This provide loosely couple within presentation layer to other layer. Ease of Scalability. • Diagram below is a high level of architecture of proposed Agrovoc WB v2.0
