Thanks Sergio - I understand the situation. We are deciding on an LDP
platform to use, and looking closely at Marmotta. We'd be willing to
contribute if we choose this project after testing further.
I noticed on the LDP tab in Marmotta, support is marked as experimental,
but the docs indicate as o
Hi,
Marmotta used to be driven by arather small core of developes thar were
backed by commercial interests. Unfortunately our daily jobs have moved all
of us to other areas. So I guess unless there is someone (person and/or
organization) with real interest on pushing Marmotta forward, this dormant

Hi all.
I have faced similar performance issues with my Marmotta 3.4.0 setup using
Postgres 9.3. My dataset had almost 30M triples divided into 10 graphs and
querying turned into an extremely slow operation in some cases. In order
to deal with it I manually added some indexes in the database sche

Hi Noor,
Thanks for reaching out! Our needs are to be able to store multiple
Datasets (fragments), with versioning, transactions, SPARQL queries, REST
endpoints for at least querying and updating, and some kind of persistence
back-end we can back-up safely. Basically, we need git for RDF :)

Hi Alan,
What type of LDP server are you looking for ? Do you need read capability
or write capability as well ? Because, in the last european semantic web
conference, I presented an approach for automating generating LDPs from
existing data sources. The LDPs can be hosted on any compatible LDP se
Thanks for the info... we may be looking to use Marmotta for a project but
was concerned about some the bugs I've encountered out of the box. For
example, mysql doesn't seem to have a 'triples' table when I select that
for the KiWi back-end... I had to create this manually. And even the
Postgres se
Hello all,
We can propose something for GSoC 2019 with the aims of reviving the project
and attract contributors. What do you think Jakob?
I can try to finish the migration to RDF4J if I find some free time. :D
In the meantime Alan, if you'd like to contribute with something the migration

Hi Alan,
I'd say dormant, not dead.
To be frank: Development activities have been rather low in the past months.
Any help is appreciated, so if you'd like to contribute something you
are more than welcome!
Best,
Jakob

Thanks Aaron.. just to be clear.. Is Marmotta a dead project now? There was
just a release in June for 3.4.0 so I hoped there'd be some momentum.. any
plans for future work here?

Hi,
if you are looking for an LDP server, the Apache Annotator project (Web
Annotation Protocol sits atop LDP) has a list of implementations on this
page:
