Hi Geoff I have started creating some project descriptions for the DAS ideas listed on the referenced wiki page. Please find my draft at : http://wiki.apache.org/ws/Tuscany/TuscanyJava/DAS_Java_Overview/DAS_Subprojects Please let me know if you want any specific type of contents to help you sell the ideas to the university/students. - Luciano Resende
Looking at the first item * * *C++ DAS* Today, Tuscany C++ SDO work in conjunction with SDOHelper to map back-end data representation to Service Data Objects. There is a need for a C++ DAS implementation that would interop with the C++ SDO and mediate between the SDO and the back-end store. Could explain a little more about this? What is the SDOHelper? I'm not aware that SDO for C++ has an SDOHelper. And for the second item *XML DAS* Currently, Tuscany DAS only support RDB back-ends, altough the idea is that DAS could access and mediate data trough various backends representations, XML being one of them. This project consists in designing the DAS implementation over XML, how the commands would be structured (e.g using XQuery, XPath, etc) and also contribute important feedback to a possible DAS spec. I'd like to check that I understand this correctly. SDO already has an XMLHelper that will read an XML document and generate a data graph. I think you mean a DAS that will selectively read fragments of an XML document and generate data objects corresponding to those fragments. Is that somewhere near? If so, I think that's the sort of thing that would work well as a student project. Thanks and regards, Geoff.
