A proposal for a standard CORBA interface for genome maps.

MOTIVATION: The scientific community urgently needs to standardize the exchange of biological data. This is helped by the use of a common protocol and the definition of shared data structures. We have based our standardization work on CORBA, a technology that has become a standard in the past years and allows interoperability between distributed objects. RESULTS: We have defined an IDL specification for genome maps and present it to the scientific community. We have implemented CORBA servers based on this IDL to distribute RHdb and HuGeMap maps. The IDL will co-evolve with the needs of the mapping community. AVAILABILITY: The standard IDL for genome maps is available at http:// corba.ebi.ac.uk/RHdb/EUCORBA/MapIDL.htm l. The IORs to browse maps from Infobiogen and EBI are at http://www.infobiogen.fr/services/Hugemap/IOR and http://corba.ebi.ac.uk/RHdb/EUCORBA/IOR CONTACT: manu@infobiogen.fr, tome@ebi.ac.uk

The Radiation Hybrid Database.

Since July 1995, the European Bioinformatics Institute (EBI) has maintained RHdb (http://www.ebi.ac.uk/RHdb/RHdb.html ), a public database for radiation hybrid data. Radiation hybrid mapping is an important technique for determining high resolution maps. Recently, CORBA access has been added to Rhdb. The EBI is an Outstation of the European Molecular Biology Laboratory (EMBL).

A CORBA server for the Radiation Hybrid DataBase.

Modern biology depends on a wide range of software interacting with a large number of data sources, varying both in size, complexity and structure. The range of important databases in molecular biology and genetics makes it crucial to overcome the problems which this multiplicity presents. At EMBL-EBI we have started to use CORBA technology to support interoperability between a variety of databases, as well as to facilitate the integration of tools that access these databases. Within the Radiation Hybrid DataBase project we are confronted daily with the interoperation and linking issues. In this paper we present a CORBA infrastructure implemented to access the Radiation Hybrid DataBase.

PALM--a pattern language for molecular biology.

This paper presents a new pattern language, PALM, for describing patterns in molecular biology sequences. The language is intended for representing knowledge about such patterns in a declarative, clear and concise way. It is also shown that its expressive power enables the definition of any regular or context free language, and also higher languages in the Chomsky hierarchy by parameter attachment, variables and procedural attachment. It is also possible to define approximate patterns. The language is rigorously defined, and several examples of its use and expressive power are given.
