I think it's safe to say that XPath did take off :) Probably the most from all the XML technologies.

This is extremely cool, I want to play around with it and hopefully contribute!

How can we query observations from multiple dataset? Like "?sub a qb:Observation ; qb:dataSet <anylink> or <anylink> ."

It seems that "Semantic Web" has become more like a sect. This technology is more than 20 years old, which was mainly pushed by the “computational logic”/”semantic” community. In turn, RDF(s)/OWL as well as SPARQL are too academic and too far away from any practical applicability. Furthermore, it does not map to any proper Object Model in most of OOP languages (owlready2 in Python may be an exception), i.e., you have to work with “Subject”/”Predicate”/”Object”. So, it is quite an exaggeration to say that RDF is more understandable than CSV. Basically, RDF is a mixture of several technologies like XML DOM/HTML, which puts a lot of “textual” (sematic schema) information around each “literal” and “relation”. I.e., translation of any CSV file to RDF will explode the size of your file to one hundred times. Finally, in order to handle any RDF file you need special libraries, like RDFLib or DotNetRDF, which are far away from any standards. Conclusion = “as soon as you develop something professionally, keep away from this so-called technology”.

I am trying to learn how I can Import such turtle-files in neosemantics (plugin for neo4j) and the generated turtle-file seems to give me some wrong triples. :/ Also the example of the video.

how would I add predicates and objects in the mapping ? Are the properties the objects?

Really cool!

Man, u just made my day <3

It was helpful. I hope you could solve my issue. I have some doubt. Clear my doubt if possible. I want to insert data in a graph like, INSERT DATA { GRAPH <ontologies.yogaholydays.com/yhd#>{ yhd:ins123 gist:identifiedBy yhd:UserID; gist:uniqueText "Jesus111"; gist:hasCommunicationAddress yhd:EmailAddress; gist:uniqueText "Jesus111@gmail.com". }} and i want to select like SELECT DISTINCT ?s ?UserID ?EmailAddress { GRAPH <ontologies.yogaholydays.com/yhd#>{ ?s gist:identifiedBy ?UserIDURI; gist:uniqueText ?UserID; gist:hasCommunicationAddress ?UserEmailURI; gist:uniqueText ?EmailAddress. }} I could get the result for first time. if i Insert and userID and Email Address for the second record and if i try to access one record by UserID, i get more than one record with all possible count of matching the data. Kindly help me in fixing this issue.
