Re: [Tracker] A question regarding to tracker

Thanks a lot, I will try it.
Another question: how can I get all MediaListEntry of <urn:uuid:image-album-1> in one SPARQL SELECT since 
there might be nfo:position xxx images inside one album.

hi Huan,

 you should use Uris to link the things (in this case images in an
album) instead of syntactic matching of text.

 i cannot check the ontology now, but your image album should look
more or less like this:

#images already available in tracker
<urn:uuid:image-1> a nmm:Image .
<urn:uuid:image-2> a nmm:Image .

<urn:uuid:image-album-1> a nmm:ImageList ;
                           nie:title "holidays in cancun".

<urn:uuid:image-album-1> nfo:hasMediaListEntry [ a nfo:MediaListEntry;
nfo:position 1; nfo:content <urn:uuid:image-1>] .
<urn:uuid:image-album-1> nfo:hasMediaListEntry [ a nfo:MediaListEntry;
nfo:position 2; nfo:content <urn:uuid:image-2>] .

regards,

ivan
