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}" ;
.

Numbers Array embbeded: 

arlise:Station1
 rdf:type arlise:SoRE ;
 arlise:hasArrayE 
      [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 Embedded: 

arlise:Station1
 rdf:type arlise:SoRE ;
 arlise:hasListE [1,5,10,15,22,24,25,18,17,10,5,0] ;
.


Numbers Array: 

arlise:Station1
 rdf:type arlise:SoR ;
 arlise:ArLeSeq_Multi "{'Mike':4,'Peter':5,'Gregg':8,'Tim':6}" ;
.

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";

JSON-LD object

resource1 lotico:ArLiSeq_JSON-LD "%7B%0A%20%20%22%40context%22%3A%20%22https%3A%2F%2Fjson-ld.org%2Fcontexts%2Fperson.jsonld%22%2C%0A%20%20%22%40id%22%3A%20%22http%3A%2F%2Fdbpedia.org%2Fresource%2FJohn_Lennon%22%2C%0A%20%20%22name%22%3A%20%22John%20Lennon%22%2C%0A%20%20%22born%22%3A%20%221940-10-09%22%2C%0A%20%20%22spouse%22%3A%20%22http%3A%2F%2Fdbpedia.org%2Fresource%2FCynthia_Lennon%22%0A%7D";


Access Method Examples

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

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