We can't agree with your claim that this project doesn't
suit the hackathon and that performance is not an issue.
I am not saying that performance isn't an issue. I am saying, in
regards to an ontology themed hackathon there are more important
issues in the realms of:
1. data access
2. data integration and remixing
3. data quality assessment and adjustments
4. inference and reasoning as drivers re. 1-3 above.
For example, "Reference Data for Anime and Manga" Hackathon
project a couple of days ago run into query performance issues.
They have created an RDF data, but couldn't work with it. They
spend a bunch of time optimizing the store performance to make
the ontology-based queries workable solution.
We host a Linked Open Data cache [1] comprised of 50 Billion+ RDF
statements, on a whim, I can load an useful dataset into that
instance for the entire planet to query (on an ad-hoc basis) as each
user sees fit. This has been the case for years.
Another argument. We all know 3Vs (volume, variety and velocity)
in a definition of big data. Velocity is already there.
Again, why do you think this is news to an organization that's
obsessed with every aspect of DBMS performance and scalability? Our
live instances [2][3][4] have always been available to hackathons
dating back to the inception of DBpedia and the Linked Open Data
cloud it helped bootstrap.
We all believe that the moment all performance issues
for RDF tools are resolved - the world would immediately
switched to RDF and don't remain stuck with rigid relational
model.
Again, performance is a none issue in our world. There are many
issues you are yet to encounter and tackle in your product. To
understand what I mean I would encourage you to emulate DBpedia,
URIBurner, or the Linked Open Data cache. Each of these is a
Virtuoso instance, so if I am to taking your claims seriously, in
the slightest, you can an least put out such an instance.
The Big Data is is an intersection of problems, not a single
problem. I would never pitch Virtuosos high-performance and massive
scalability as the solution to the aforementioned intersection of
problems. The real solution lies in the ability to loosely couple
the following:
1. Identifiers
2. Entity Relations (Data)
3. Entity Relations _expression_ Syntax & Notations
4. Entity Relations Serialization Formats
5. Databases (Datasets)
6. Database Management Systems.
Get 1-6 sort and we don't have a Big Data problem at all.
We are a small company, but we are developing and perfecting our
NitrosBase technology for more than 20 years. Our products are
the demonstration of our algorithms and technology features. We
are open for cooperation. Now we are talking with dot15926 team
on integration of our tools. We can cooperate with all
interested teams to improve tools for all community.
Fine, but don't make careless presentation of benchmark claims that
involve 3rd party products. There are best practices for performing
and presenting benchmarks results.
BTW -- There is an LDBC [5] effort in place for any organization
interested in the construction and use of benchmarks aimed at graph
model oriented databases. You will have a lot of cooperation on the
table if you get involved etc..
