You can start querying for stuff, but I am guessing that what you mean is how can you find out what is in the store without starting to query.
Well if you are lucky: There is a sitemap.xml, which points you at a voiD document that tells you some of what you want to know, such as what the topics of the dataset are. For example, our http://acm.rkbexplorer.com/ has http://acm.rkbexplorer.com/sitemap.xml which points at http://acm.rkbexplorer.com/models/void.ttl Or you might be able to find the voiD document some other way. I'm afraid you are unlikely to be lucky, though - not many people publish voiD data. (A while ago we tried to harvest it, and you will find the results at http://void.rkbexplorer.com) Also, looking in the catalogue at http://datahub.io/ may provide information you can use.
