....for a public tool interface for an open repository [23,30] doesnot include such query facilities. Rather the usual access to objects is bynavigation. PCTE has no facilities to state queries against the OMS in a descriptiveway. To fill this gap, some proposals for query languages have been made [28, 1, 14], but these proposals are only concerned with traditional fact retrieval. Since the data stored in a repository is usually made up of documents like requirements documents, OOA Diagrams, module specIn: Proceedings of the 19th Annual International ACM SIGIR Conference on Research and Development ....

....first ideas for a query language are sketched together with more general considerations on an information retrieval common service for PCTE. In this work the need for a pattern matching facility is stressed as an important but open issue. Two interesting query languages for PCTE are presented in [1]. PNQL is an approachforanavigation oriented query language using path expressions extended by predicates and output definitions. PQL has an SQL likesyntax, but is nevertheless largely navigation oriented. Both languages do not contain document retrieval facilities. 2 As mentioned in the ....

....Such tools often provide very polished user interfaces and software development facilities, but are notoriously difficult to extend and integrate with thirdparty tools. Tools using a database and database views to support data management and data viewing and editing include PCTE based systems [4], SPADE [3] and EPOS [7] The database provides a unifying data integration mechanism, but message passing is often employed to facilitate control integration. Process centred environments, such as SPADE, EPOS and ProcessWEAVER [11] support process integration by providing software process ....

....are generally not supported, with the notable exception of DV Centro. The compositional metaphor of BBW also allows designers to extend its built in iconic, connector and constraint components for reuse. Dynamic visualisation and repository querying tools include those of Teorey et al. [16] Bird [20], Consens and Mendelzon [24] and metaEDIT [5] Most use either graphical query languages, with results presented textually, or textual query languages with textual or graphical results. We have found the JVisualise approach of graphical structure representation and textual constraints, plus ....

....a join operator or a cartesian product in order to achieve object preservation. SQL like query languages always use a kind of cartesian product. They are therefore not object preserving. Among a whole variety of SQL like proposals for ER query languages, there exist also two for PCTE, namely PQL [1] and P OQL [7] 4.3 Other PCTE Query Languages The first PCTE specific approach to a set oriented query language is called Data Query and Manipulation Service DQMCS [17] It comes together with PACT [12, 18] a commercial software engineering environment on top of PCTE.

....to implement document specific retrieval functionality, similar to grep in UNIX. To this end, the application (tool) programmer has to declare the retrieval relevant attributes of a document statically; this corresponds to a kind of view upon the data schema. The Pathname Query Language PNQL [1] was the first approach that indeed offers an interactive front end for a set oriented query language on PCTE. The basic idea is to extend the usual navigational access to a set oriented navigation by using link pattern instead of normal link names. The result of a query is a value table. PNQL has ....

....components in an appropriate manner. They do not however provide visual event handling configuration. Visual query languages have been developed for both database and CASE tool repository inspection. Examples include graphical querying of ER models [4, 20] and CASE tool repository querying [17, 1]. Such approaches to visual querying usually attempt to fully formulate queries visually [17, 4] but often present results in a conventional textual manner. We took the approach of allowing users to use the JVisualise notation for queries, with component structures queried visually but attribute ....
