Newbee issues sd5

  1. Took me some time to find the way to import data. It is hidden under "Browse" after which you get a menu of browse (again, and data etc. isn't that a bit strange? (could it be a webbrowser issue? I am using Chrome).

  2. After importing some ttls I can query but there is no result when browsing.

    Some help/tips very much appreciated.

Sorry for these very newbee questions (my ref. till now is graphdb).

Greetings Michel

I can see how that might be a little confusing. The first time you see “Browse” is probably from the “Stardog Admin” page after selecting the database you have the option to “Browse” or “Query” that take you to the database specific “Schema Browser” or “Query Panel” pages and from there you have the additional option of “Data” which includes “Add”, “Remove”, and “Export”.

I’m not a UI person but I suppose there is no reason why there can’t be a “Data” option on the admin page and it might make the navigation more consistent. (I’m just throwing that out there as a suggestion)

Can you give the options that you used to create the database. If you used the WebConsole you can just list anything you selected different from the defaults. Can you share the data you loaded and how you loaded it?

Welcome to Stardog.

Hi Michel,

Well, as I was typing out a response, Zach pretty much said what I was going to say. I can add that if you navigate directly to the “home” page of a specific database (e.g., http://localhost:5820/myDb), the Query/Browse/Data menu will be displayed there. I agree it’s not ideal that getting there via the Admin page doesn’t display it.

and wrt “browse”…I think it would already help if the first Browse (the broad one including the schema-browse and Data etc.) got a broader name.

Can you share the data that you’re loading?

cmo.ttl (3.1 KB)
simple.ttl (3.0 KB)

cmo also imports some (3) subontologies (QUDT) that I did not upload...could THAT be the problem?ADAPTED_VOCAB_QUDT-BASE-QUANTITY-KINDS-v2.0.ttl (47.3 KB)
ADAPTED_SCHEMA_QUDT-v2.0.ttl (118.7 KB)
ADAPTED_VOCAB_QUDT-UNITS-SPACE-AND-TIME-v2.0.ttl (202.4 KB)

tHINK THAT WAS IT! i NOW SEE ALL STUFF…or it was already fine but I clicked the entity name instead of the plus…

Stardog doesn’t automatically load ontologies referenced with owl:imports

“Follow ontology owl:imports statements automatically; any imported OWL ontologies that are required must be loaded into a Stardog database in the normal way.” – http://www.stardog.com/docs/#_known_issues

ok thanks, fully clear now!

The “+” will expand the tree and list any direct subclasses and clicking on the name will take you to a page for that class with a link to view the definition and a list of any class members. “No more elements found!” means there are no instances. That may be a somewhat confusing message.
