Ivan Her­man—Soft­ware De­vel­op­ments

(Ob­vi­ously, these are only the major soft­ware de­vel­op­ments, and only of the past 15-20 years; pre­vi­ous pro­jects have no trace on the Web…)

• rd­fjs-c14n, a stan­dard-con­form im­ple­men­ta­tion of the W3C RDF Dataset Canon­i­cal­iza­tion (RDFC-1.0) stan­dard, writ­ten in Type­Script.
• ym­l2vo­cab, a pack­age used to gen­er­ate RDFS vo­cab­u­lary files from YAML. It is not a com­plete so­lu­tion for au­thor­ing vo­cab­u­lar­ies, it is meant for sim­ple vo­cab­u­lar­ies and to be used by peo­ple who are not RDF vo­cab­u­lary ex­perts. It gen­er­ates the vo­cab­u­lar­ies in Tur­tle, JSON-LD, and in HTMML+RDFa. Writ­ten in Type­Script.
• r2epub, pro­gram to con­vert W3C doc­u­ments, pro­duced by Re­Spec, to EPUB 3.2. A pub­lic ser­vice is also avail­able for that pur­pose, using this mod­ule.
• SPAR­QL­Wrap­per, a wrap­per around a SPARQL ser­vice for Python. Moved to Source­Forge, under the watch­ful eyes of Ser­gio Fer­nan­dez and Car­los Tejo, who are now main­tain­ing the pack­age. It has also be­come part of the stan­dard De­bian dis­tri­b­u­tion.
• pyRdfa, an RDFa 1.1 dis­tiller on top of Python’’s RD­FLib pack­age. The mod­ule is also de­ployed as an on­line RDFa dis­tiller ser­vice. This mod­ule is part of the col­lec­tion of the pack­ages us­able with RD­FLib.
• pyMi­cro­data, an Mi­cro­data to RDF soft­ware on top of Python’’s RD­FLib pack­age. The mod­ule is also de­ployed as an on­line Mi­cro­data to RDF dis­tiller ser­vice. This mod­ule is part of the col­lec­tion of the pack­ages us­able with RD­FLib.
• SPARQL en­gine for Python, in­cluded in RD­FLib pack­age. Michel Pel­letier and Chimezie Og­buji added an SPARQL Lan­guage parser, too, yield­ing a SPARQL im­ple­men­ta­tion for Python.
• OWL RL mod­ule on top of Python’s RD­FLib. The func­tion in the mod­ule cal­cu­lates the Clo­sure graph, fol­low­ing the spec­i­fi­ca­tion of the OWL 2 RL pro­file. It is also avail­able on pip. At some point, the pack­age’s main­te­nance has been taken up by Nicholas Car
• Graph Vi­su­al­iza­tion Frame­work (GVF), also re­ferred here and there as “Royere”, de­vel­oped with Scott Mar­shall and Guy Melançon. It is cur­rently at Source­Forge, and it has gone its own way by now…
