20 Mpping DDI-XML to Disco

21 Mpping DDI-XML to Disco Mppings only between Disco nd DDI 3.1 of DDI-L in order to void inconsistencies existing mpping documents between DDI 3.1 nd other DDI versions (like DDI 3.2 nd DDI 2.1) cn be reused Avilbility Google Doc with mpping tbles s bsis for utomtic genertion Turtle file contining ll mppings Mpping tbles in HTML specifiction of Disco Mpping is still ongoing work

22 XSLT for existing DDI-XML XSLTs for converting ny XML output of DDI-C nd DDI-L re vilble t Different XSLT for DDI-C nd DDI-L

23 Bidirectionl Mppings Only between Disco nd DDI-L DDI-L Disco: stright-forwrd mpping for ll items used in Disco Disco DDI-L: stright-forwrd mpping for ll items in the disco nmespce. Only stndrd XPth expression is defined s mpping Context: Items from other vocbulries - used in Disco - need context; then there could be cler mpping pth. Context informtion necessry for mppings, e.g., skos:nottion cn be mpped to vrible lbels nd to codes. Context informtion is either SPARQL query or n informl description s plin literl.
