It seems the api and implementation are still in progress.
Is LdpService.java supposed to conform to the W3C working draft in 2013-07

recommendation?
Nandana already did a great summary of the following steps of LDP at
W3C. I expect the timing would fit quite well with GSoC's timeline, and
by the end of April everything should be stable enough.
But I'd say for your project the uncertainty is even smaller:
MARMOTTA-440 is defining the stubs for the rest web services, which
pushes requirements to fully define the LdpService interface. Therefore
your project would target a concrete implementation of that interface.
You should not care about other details around; although, of course, any
feedback would be always welcomed to improve the whole stack.
Now, I can totally understand the source code of Sesame-native
implementation. I have good knowledge of SPARQL 1.1. With Sesame, I can
write codes of SPARQL Query for LdpService.exists() and getStatements(),
while SPARQL Update [3] for LdpService.addResource() and deleteResource().
As to LdpService.exportResource() and generateETag(), it's just required to
translate the inline getStatement() codes into SPARQL queries. Am I right
about the above approaches?
Complete right: SPARQL 1.1 implementation of those methods. For the
moment are few, but it'll still evolving and the list will grow for sure.
We use industry standards: git for code control, maven as build tool,
junit and rest-assured for testing, Weld for CDI, etc. But don worry if
your are not some familiar with any, because in case your proposal gets
granted, a mentor will be assigned to help during the project execution.
Thanks for telling me about these. I'm familiar with maven and junit. As to
git and Weld, I've just started to learn their documents. Is rest-assured
the one here [4]?
Exactly that. It provides a very nice DSL for REST testing. See for
instance this test:
https://git-wip-us.apache.org/repos/asf?p=marmotta.git;a=blob;f=platform/marmotta-ldp/src/test/java/org/apache/marmotta/platform/ldp/webservices/LdpWebServiceTest.java;h=4883e8bee28a16978ec82ac88dc06caf5c50bd1d;hb=refs/heads/ldp#l90
Although not included in the description, testing is very important for
us. Therefore it is expected you would also help extending that test
suite, in order to improve the validation of your implementation.
Thanks for your interest. Please, let us know if you may need anything
else for the proposal preparation.
Cheers,
