This paper in Bioinformatics points to a project on SourceForge.
The project is to develop a SOAP/Axis based query service for DNA microarrays. Hopefully you will be able to incorporate microarray data into all your apps regardless of platform!
Microarrays are an important research tool for the advancement of basic biological sciences. However this technology has yet to be integrated with clinical decision making. We have implemented an information framework based on the Microarray Gene Expression Markup Language (MAGE-ML) specification. We are using this framework to develop a test-bed integrated database application to identify genomic and imaging markers for diagnosis of breast cancer.
