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:

SELECT avg(?array)
WHERE{
 ?resource arlise:hasArray ?array
}
SELECT ?array[1]
WHERE{
 ?resource arlise:hasArray ?array
}
