* Richard Cyganiak <richard@cyganiak.de> [2011-11-20 00:00+0000] > I didn't read more than the abstract, but this Adobe patent looks at least *slightly* related to the Direct Mapping. Filed in 2009. Anyone care to summarize what's being claimed? I don't think I understand "third triples". I believe first and second are indeed what we produce in the DM: DM generates [[ <People/ID-7> rdf:type <People> . <People/ID-7> <People#ID> 7 . <People/ID-7> <People#fname> "Bob" . <People/ID-7> <People#addr> 18 . ]] Adoble generates something like: [[ # "first triples corresponding to data specified within tables in the relational database" # <People/ID-7> <People#ID> 7 . @@missing per "an object including non-primary-key information from the given row" <People/ID-7> <People#fname> "Bob" . <People/ID-7> <People#addr> 18 . # "second triples corresponding to data links between the tables in the relational database" <People/ID-7> <People#ref-addr> <Addresses/ID-18> . ]] Per "at least one of the primary key constraint definitions, at least one of the foreign key constraint definitions, and an associative mapping table corresponding to the relational database" perhaps third look like: [[ <People/ID-7> <somePredicate> <Addresses/ID-18> ]] ? Note, I've not see the figures. I haven't even seen what @#$%ing media type they are. Perhaps it's a Windows world. > http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PALL&p=1&u=%2Fnetahtml%2FPTO%2Fsrchnum.htm&r=1&f=G&l=50&s1=8037108.PN.&OS=PN/8037108&RS=PN/8037108 > > Shortened URL: http://1.usa.gov/vwEN7z > > Best, > Richard -- -ericP
