Hello Sebastian,

First thanks a lot for the reply. I started to believe that what I was saying was complete nonsense.

Hi Amirouche,

Any open data projects that are running open databases with FoundationDB and WiredTiger? Where can I query them?

 

Thanks for asking. I will set up a wiredtiger instance of wikidata. I need a few days, maybe a week (or two :)).

I could setup FoundationDB on a single machine instead but it will require more time (maybe one more week).

Also, it will not support geo-queries. I will try to make labelling work but with a custom syntax (inspired form SPARQL).

I figured that anything that is not SPARQL will not be convincing. Getting my engine 100% compatible is much work.

The example deployment I have given in the previous message should be enough to convince you that

FoundationDB can store WDQS.

Don get me wrong, I don want you to set it up. I am asking about a reference project, that has:

1. open data and an open database

2. decent amount of data

3. several years of running it.

Like OpenStreetMap and PostreSQL, MediaWiki/Wikipedia -> MySQL, DBpedia -> Virtuoso.

This would be a very good point for it. Otherwise I would consider it a sales trap, i.e. some open source which does not work really until you switch to the commercial product, same for Neptune.

Now I think, only Apple knows how to use it. Any other reference projects?
