Towards practical meta-querying
نویسندگان
چکیده
We describe a meta-querying system for databases containing queries in addition to ordinary data. In the context of such databases, a meta-query is a query about queries. Representing stored queries in XML, and using the standard XML manipulation language XSLT as a sublanguage, we show that just a few features need to be added to SQL to turn it into a fully-fledged meta-query language. The good news is that these features can be directly supported by extensible database technology.

متن کاملExtending a UML and OCL Tool for Meta-Modeling: Applications towards Model Quality Assessment
For developing software in a model-driven style, metaand multi-level modeling is currently gaining more and more attention. In this contribution, we propose an approach to extend a two-level modeling tool to three-level modeling by adding a meta-model at the topmost level. Standard OCL does not support reflective constraints, i.e., constraints concerning properties of the model like the depth o...
متن کاملTowards Using OCL for Instance-Level Queries in Domain Specific Languages
The Object Constraint Language (OCL) provides a set of powerful facilities for navigating and querying models in the MOF metamodelling architecture. Currently, OCL queries can be expressed only in the context of MOF metamodels and UML models. This adds an additional burden to the development and use of Domain Specific Languages, which can also benefit from an instance-level querying mechanism. ...
متن کاملTowards a Unifying Approach to Representing and Querying Temporal Data in Description Logics
Establishing a generic approach to representing and querying temporal data in the context of Description Logics (DLs) is an important, and still open challenge. The difficulty lies in that a proposed approach should reconcile a number of valuable contributions coming from diverse, yet relevant research lines, such as temporal databases and query answering in DLs, but also temporal DLs and Seman...
متن کاملMusic Similarity Analysis in a P2p Environment
In this paper we present our work towards an integrated P2P platform for convenient music retrieval. The main goal is to provide a distributed computation and storage of basic music features from MP3 encoded files and/or sources on the web. In this way we try to resolve the problem of missing meta data in order to provide intelligent services for convenient music querying. We believe that such ...
