Hello Nepomuk,<br>
<br>
we are interested to use SesameSail but we encountered an issue. We
sent yesterday an email to sesame discusssion list while we seek
help to optimize it, but it seems the product is not further
developed, although I noticed a newer LuceneSail version has been
updated 10 months (<a href="https://github.com/kreuzverweis/lucene-sail-3.0" target="_blank">https://github.com/kreuzverweis/lucene-sail-3.0</a>).<br>
<br>
<div>Can you please confirm wheather
the product is actively maintaned or not? If yes we are glad to
work with you, otherwise we have to seek for alternatives.<br></div></div></blockquote><div><br></div><div>This mailing list is for the nepomuk-kde project, which is not affiliated with DFKI.<br><br></div><div>About 4 years back we did try to use Sesame, but we eventually moved to OpenLink's virtuoso[1] in order to store triples. It has worked quite well, and can easily store 10 million triples.<br>

I am not personally involved in the LuceneSail development (it is a
project separate from Sesame, maintained by DFKI), but as far as I know
it is not actively maintained at the moment.
