Metadata Management of Models for Resources and Environment Based on Web 2.0 Technology

The papers firstly introduce the standard framework of model metadata as well as its composition, content and meaning. It is held that model metadata should consist of an identifier, sphere of application, model parameters, principles, performances, run conditions, management information, references, and case information. Then we explained the virtual community for model metadata publishing, sharing and maintaining. Finally, we expatiated on the expression of model metadata standard based on XML schema Definition (XSD), the extended-metadata based on Tag and the publishing of model metadata based on Wiki. Based on Web 2.0 technology, the traditional model metadata which just create by modeler was extended to support extended-metadata created by model users or domain experts, which includes the feedback on model evaluation and suggestion. The user-metadata was refined from massive messy individual tags, which reflect the implicit knowledge of models.
