Contribute to Marmotta in GSoC 2014 (Provide an alternative
SPARQL-based implementation of the LdpService)
Hi all,
I'm Qihong Lin from Beijing Normal University Zhuhai Campus, P.R. China. I
did some student projects in my university related to Semantic Web. I have
good knowledge of RDF, SPARQL, Linked Data, with some development
experience of Sesame and Jena. According to my background, I'd like to
contribute to Marmotta in GSoC 2014, on MARMOTTA-444 [1] (Provide an
alternative SPARQL-based implementation of the LdpService).
I also have some basic skills of SVN, Junit and Dependency Inversion. But I
didn't work on open source projects before. Marmotta would be my first open
source community to get involved, if I can get accepted. It's
greatly appreciated if you can help me with the project application and the
coding work. Now I'm studying the documents of Marmotta. I can understand
the description in MARMOTTA-444 in jira. Could you please tell me more
details about it? Is there a project proposal template to refer to?
Best,
Qihong Lin

This will depend on several things such as the comments that we will
receive and whether everyone accepts the current specification, but here is
the tentative plan for the path of W3C recommendation.
http://www.w3.org/2012/ldp/wiki/Meetings:Telecon2014.03.03#Status_Update
However, when it is at the Candidate Recommendation stage (28 April), you
could consider it to be pretty stable and the rest of the steps are more
related to W3C process to get it through as a recommendation.
Best Regards,
Nandana

Dear Sergio,
Your feedback is very valuable. Thank you! I've modified the proposal
according to your suggestions. Here's the short description inline. Any
other suggestions are very welcome.

The references of 5 and 6 have been merged to SPARQL 1.1. Also, I change
the project title to highlight SPARQL 1.1. Hope it helps.

Yes, I'm just aware of that. This performance improvement part has been

for pointing it out.

I agree with you. The project plan is now grouped by the targets (i.e.
resource, container, etc) and their functionalities. According to the new
plan, you can assess both the reading and writing capabilities of resource
in the mid-term evaluation.

Great!
Taking a quite look to your proposal, there are some points you could
improve:
* References 5 and 6 could be mentioned together as SPARQL 1.1. It is
not expected to work with SPARQL 1.0, that's something you could stand out.
* Performance Improvement: that's not true at all, because all pending
operations are performed at commit time. And I don't expect performance
would be better in this alternative implementation, we're aware of it.
* Instead you could add something about portability, since SPARQL is the
official recommendation for accessing RDF stores (Sesame is just the
de-facto standard for Java).
* LdpService definition is still evolving. So I'd not refer the delivery
of concrete methods in the work plan, but functionalities (container
creation, resource addition, resource deletion, etc) instead.
* Although I understand that reading operations could be easier for
starting, in the end data creation needs to be in place before reading.
So FMPOV you would have two options: a) group by target (resource,
container, etc.) instead of operation type (exist, read, write, etc.) b)
keep it as it is, and start with a service skeleton where all methods
call the default implementation until you provide your actual
implementation of each. I'd prefer the first, but the second is
completely valid and probably the most convenient one for you.
* But for the mid-term evaluation I'd like to have some writing
capabilities already in place, not only reading ones.
* For storing binary resources, or more precisely "LDP Non-RDF Source",
you could use the same service the default implementation uses, SPARQL
is not capable of that.
* I like that you assert that each concrete milestone would come with tests.
So far, the proposal looks good for me. Thanks for your effort.
Cheers,

Don't worry, the date there was more a wish than an actual planned date.
But that date fits with the GSoC's mid-term evaluation, which
potentially is a good checkpoint for your project.

Dear Sergio,
I have been composing the project proposal draft these days. I find some
GSoC proposal examples, most of which contain the "time table" parts. I'd
like to include the project schedule as well in my proposal.
Basically GSoC 2014 goes in this way:
----
Begin coding: 19 May
Mid-term evaluation: 27 June
End coding: 11 August
----
However I find that the due date of MARMOTTA-444 in Jira is 30 June. Does
it mean that I'm supposed to complete the work before the mid-term of GSoC
2014? If so, how about the second part of the summer in July and August? I
believe the Marmotta community has its plan of developing the Linked Data
Platform implementations. I don't want to delay your original plan because
of the GSoC program. Could you please tell me about the desired schedule?

Your contributions would be welcomed. And don't be self-conscious
because your inexperience. That's normal, it happened to everybody at
some point, it's a natural learning process. And GSoC is an excellent
program for that.

Besides the unit tests, the REST test should behavior exactly the same
when plugin your implementation instead of the default one. In principle
we're going to provide a sufficient test suite (this is related to
MARMOTTA-438 by the way), but we could also expect contributions there
for improving the coverage of testing.

Dear Nandana and Sergio,
I'm grateful to your explanations.
I'll focus on implementing the LdpSrvice interface using SPARQL.
The implementation can be developed incrementally during the GSoC 2014
summer, if anything would be changed for LdpService. I can also promise to
maintain the implementation after the GSoC program. As a student, it's
great to get involved into an open source community with long time
contributions. I believe I can learn a lot from the project experience.
According to your replies, the testing work contains 2 parts: 1) unit tests
(junit) of the SPARQL implementation itself; 2) RESTful service tests
(rest-assured). It seems the later one is service oriented, not for the
concrete implementations. Shall we test the RESTful services for different
LdpService implementations (i.e. different test cases/suits
for different implementations)?
I'm clear about the project scopes now: the SPARQL implementation and the
tests. The approaches are lucid in my mind as well. Anything else to be
considered/discussed for the project scopes/approaches/etc? If not, I'd
like to prepare a project proposal draft.

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.

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.

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.

It seems the api and implementation are still in progress.
Is LdpService.java supposed to conform to the W3C working draft in 2013-07
[1] or the latest one here [2]? When will Linked Data Platform become a W3C
recommendation?
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?

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]?

Right now Jakob and myself are working on a Sesame-native implementation
(for more details, see MARMOTTA-440 and the ldp branch on git), and we
hope to have it sufficiently evolve to give a proper working framework
for the project.
I can anticipate you it'd require quite good knowledge of SPARQL 1.1, as
well of RDF and Sesame.

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.

Sorry, this is the first time we participate in the GSoC. So we did not
prepare any project proposal template. But I think what the general
documentation describes should more than enough:
https://www.google-melange.com/gsoc/document/show/gsoc_program/google/gsoc2014/help_page#5._What_should_a_student_proposal_look
Hope this helps. Whatever other question you may have, just ask.
Thanks for your interest.
