New ideas to deal with large series of data points in RDF in the form of arrays, lists and similar data structures.
currently RDF data model proposed rdf:Bag and rdf:Seq in the form of
resource1 a rdf:Bag; rdf:_1 "1323"; rdf:_2 "1321"; .
we propose here the following additional notation for large sequences:
Numbers Array:
arlise:Station1 rdf:type arlise:SoR ; arlise:hasArray "{1:1;2:5;3:10;4:15;5:22;6:24;7:25;8:18;9:17;10:10;11:5;12:0}" ; .
Numbers List:
arlise:Station1 rdf:type arlise:SoR ; arlise:hasList "{1;5;10;15;22;24;25;18;17;10;5;0}" ; .
Strings Sorted:
- resource1 lotico:ArLiSeq_SS {1:'Mike';2:'Peter';3:'Tim;4:'Marco';....}
Strings unsorted:
- resource1 lotico:ArLiSeq_SU "{'Mike';'Peter';'Tim;'Marco;....}"
JSON object
- resource1 lotico:ArLiSeq_JSON "%7B%20%22name%22%3A%22Marco%22%2C%20%22age%22%3A30%2C%20%22car%22%3Anull%20%7D";
Access Method Examples
SELECT avg(?array) WHERE{ ?resource arlise:hasArray ?array }
SELECT ?array[1] WHERE{ ?resource arlise:hasArray ?array }
