[Virtuoso-users] load SQL data in Virtouso
hi The converting strategy DB to RDF via Virtuoso is mapping OWL class to every table, but in reality for example Person table may be divided to two table "Basic info and extended" for DB design considerations I want to make R2RML, I have a Person RDF class that is must be type of Person table, In my DB design I have Basic_Person and Extended_Person tables, not a single table that mapped to Person RDF class So must I make changes to DB design before convert it to RDF "merge Person tables into one and other changes"?? thanks -- ------- > Eng.Bassam Najeeb. >Software Engineer. -- ___ Virtuoso-users mailing list Virtuoso-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/virtuoso-users
Re: [Virtuoso-users] load SQL data in Virtouso
My problem is make map customization, so I want use my own types "owl" not a virtuoso automatic generated types for tables and columns e.g Person owl class can't be class for basic info and also to extended table too. is this right?

Re: [Virtuoso-users] load SQL data in Virtouso
additional info on previous mail : My problem is make map customization, so I want use my own types "owl" not a virtuoso automatic generated types for tables and columns e.g Person owl class can't be class for basic info and also to extended table too. the objective is make my DB published to any one, so I thinks current DB design and build RDF on it confuse the users for query e.g ?x a Pesron ?x foaf:name ?y here I want also get birth date in extended table, how I can do that the user may be write ?x foaf:birthdate ?z but this is wrong x not have direct relation to DOB, it's have relation to node that represent Person extended info and the relation to DOB is this right?

Re: [Virtuoso-users] load SQL data in Virtouso

Re: [Virtuoso-users] load SQL data in Virtouso
thanks Idehen sorry about my pretty questions, but I'm beginner in Virtuoso :) I have understood the SQL views better solution than modify DB ERD, but what about Primary and Foreign keys to links nodes in RDF e.g emplyee and his department?? is this can be done in R2RML code manual?? Note: my project strategy is generate R2RML by virtuoso "auto generate" and then modify it to custom OWL classes, then I will upload R2RML in virtuoso to make custom mapping as described here http://docs.openlinksw.com/virtuoso/r2rml.html#r2rmlgentransperslviewrs thanks On Mon, Nov 9, 2015 at 3:38 PM, Kingsley Idehen wrote: > On 11/8/15 4:42 PM, Eng.Bassam wrote: > > So Idehen, I think must make refactoring to my DB to be converted to RDF > using my owl classes and R2RML code > is this right?? > > > You don't refactor your DBMS per se., what you do is make you own custom > mappings in your R2RML.

the file R2RML attached also by this mail
I want understand why the output R2RML in patient make the child is patient
and parent is dianoses.?
diagnoses table it is has FK so I thinks it is a child and Patient it 's a
parent, opposite to output !!!

the parent table here in my example is Patient which has ID primary Key
the child table is the Diagnoses which has foreign key is Patient ID
now the R2RML must make a join condition to link child table (Diagnoses)
with it's parent (Patient)
the condition is in sql ( Diagnoses,PatientID = Patient.ID)
but in generated R2RML by virtuoso is make the child -->parent and make
parent-->child
rr:joinCondition [ r*r:child "ID" ; rr:parent "PatientID" *] ; ]; ]
i.e I think the generated r2rml must be opposite:
rr:child "PatientID" --- not ID
rr:parent "ID" not PatientID
because the PatientID is a column in child table(diagnoses) and ID is a
column in Parent table (Patient).
right???
this what I have understood from http://www.w3.org/TR/r2rml/#example-fk
sorry again about long questions and thanks :)

Re: [Virtuoso-users] confusing in rr:joinCondition generated by virtuoso ??
thanks again
waiting a fix a problem
if you want more simple example (dept & emp) it's in attachment file also,
as you will see the file has R2RML not same as W3 example
at http://www.w3.org/TR/r2rml/
if apply the emp & dept example on virtuoso and to get RDF graph, we will
see the emp triple has reference to department (it's right) but also the
dept has triples for it's emloyees (wrong sure there is no key in DB from
Dept to employee)
I wish it's clear description and thanks a lot to answer me :)

Re: [Virtuoso-users] [virtuoso-opensource] Accessing Virtuoso from C#? (#512)
Hi
for developers who want to access virtuoso via C#, I do the following:
1- add connection string at app settings
2- using virtado4.dll ADO's classes after reference it
string conString =
System.Configuration.ConfigurationManager.ConnectionStrings["MYCONN"].ConnectionString;
VirtuosoConnection virtuosoSrv = new
VirtuosoConnection(conString );
virtuosoSrv .Open();
VirtuosoCommand cmd = new VirtuosoCommand("sparql SELECT
?termURI FROM <http://localhost:8890/ontologies/geonames> WHERE { ?termURI
?z ?y.} LIMIT 10", virtuosoSrv );
VirtuosoDataReader countryDataReader = cmd.ExecuteReader();
while (countryDataReader.Read())
{
String col = countryDataReader.GetString(0); // make
something
}
wish it's usefull :)

[Virtuoso-users] Make my views refer to external ontology?
Hello I have a person pesron table with columns (id, name , country_geo), person table type in R2RML is foaf:person, I have also loaded geonames onology in my virtuoso server at link http://localhost:8890/ontologies/geonames now for the country_geo column the r2rml is : rr:predicateObjectMap [ rr:predicateMap [ rr:constant SIO:SIO_000664 ] ; rr:objectMap [ rr:column "Country_geo" ]; ] ; the value of country_geo is IRI e.g "http://sws.geonames.org/2378080/"; described in my loaded ontology geonames. now how can I make the generated country_geo property in person refer to my loaded ontology geonames, what should I write in r2rml ??? my objective is making sparql queries on the generated views (persons) and traverse to geonames for more info about countries. wish it's clear question :) thanks -- --- > Eng.Bassam Najeeb. >Software Engineer. -- ___ Virtuoso-users mailing list Virtuoso-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/virtuoso-users

Re: [Virtuoso-users] Make my views refer to external ontology?
thanks
I thinks only must write FROM statement to include local ontologies in my
sparql or to inform sparql engine where can locate the data, i.e:
select ?o ?cname
FROM <http://localhost:8890/ontologies/mydata> //my persons data
FROM <http://localhost:8890/ontologies/geonames> // geo country data
where {?s SIO:SIO_000664 ?o;
?s a foaf:Person.
OPTIONAL { ?o gn:name ?cname. }
}
limit 10
right?

Re: [Virtuoso-users] Make my views refer to external ontology?
Hi Kingsely and all members
still there is the same problem can't traverse from ontology to other cause
the generated IRI is text not IRI type, next is the description and sorry
to be long but it's a problem need to solve ASAP to complete my project
As I have said I have imported SQL DB using custom R2RML:
<#TriplesMapPerson> a rr:TriplesMap; rr:logicalTable [ rr:tableSchema
"dataMaster" ; rr:tableOwner "data-ODBC" ; rr:tableName "Person" ];
rr:subjectMap [ rr:termType rr:IRI ; rr:template "
http://localhost:8890/dataMaster/person/PersonID={ID}";; rr:class
sio:SIO_000393; rr:graph <http://localhost:8890/dataMaster#> ];
rr:predicateObjectMap [ rr:predicateMap [ rr:constant sio:SIO_000664 ] ;
rr:objectMap [ rr:column "Country" ]; ] ;
the column Country contain the IRIs of country geo ontology i.e as
http://sws.geonames.org/226074/, this ontology I have loaded in my Virtuoso
server at
http://localhost:8890/ontologies/geonames
this local ontology have rdf resources as :
http://sws.geonames.org/226074/
<http://sws.geonames.org/2378080/>">
http://sws.geonames.org/226074/about.rdf
<http://sws.geonames.org/2378080/about.rdf>"/>
USA
now my query is :
PREFIX sio: <http://semanticscience.org/resource/>
prefix gn: <http://www.geonames.org/ontology#>
select ?country
FROM <http://localhost:8890/dataMaster#>
FROM <http://localhost:8890/ontologies/geonames>
WHERE { ?s a sio:SIO_000393.
?s sio:SIO_000664 ?country.
}
the result unfortunately is the IRIs but in quotation as a text not an IRI
type i.e "http://sws.geonames.org/226074/";, so I can't add to where clause
in my query ?country gn:name ?cname also can't do ?country a gn:Feature
PREFIX sio: <http://semanticscience.org/resource/>
prefix gn: <http://www.geonames.org/ontology#>
select ?country
FROM <http://localhost:8890/dataMaster#>
FROM <http://localhost:8890/ontologies/geonames>
WHERE { ?s a sio:SIO_000393.
?s sio:SIO_000664 ?country.
?country gn:name ?cname// *this
triple make a traverse to other local ontology (geonames)*
}
I think the problem is :
generated country property is text not IRI type.
I have try to modify the my R2RML using IRI template as
rr:predicateObjectMap [ rr:predicateMap [ rr:constant sio:SIO_000664 ] ;
rr:objectMap [ rr:termType rr:IRI ; rr:constant gn:Feature; rr:template
"{Country_geo}" ]; ] ;
but also fail the generated IRI "need an encoding"as
http%3A%2F%2Fsws.geonames.org%2F226074%2F
<http://localhost:8890/conductor/http%3A%2F%2Fsws.geonames.org%2F226074%2F>
wish to give me a solution :)
thanks

Re: [Virtuoso-users] Make my views refer to external ontology?
Hi
I have tried this solution many times but unfortunately it's fail
the generated IRI by virtuoso as "http%3A%2F%2Fsws.geonames.org%2F226074%2F
<http://localhost:8890/conductor/http%3A%2F%2Fsws.geonames.org%2F226074%2F>
"
now to solve this problem temporary, I' using rr:column not template for
IRI for this situation,
I'm using IRI function then to convert the "http://sws.geonames.org/226074";
text to IRI in filter clause
like this
select ?countryName
where
{
GRAPH <http://localhost:8890/emrMaster#>
{
?patient sio:SIO_000664 ?country.
}
GRAPH <http://localhost:8890/ontologies/geonames>
{
?geo gn:name ?countryName.
}
FILTER(IRI(?country) = ?geo) .
}
GROUP BY ?countryName
is it a bug ??? or something wrong ???
thanks again

Re: [Virtuoso-users] Make my views refer to external ontology?
OK, so I will still using a temporary solution
Now when this bug will be fixed also I inform you a bug from 1 week about
auto generated R2RML file (child and parent column) ??? also How can I get
notification these fixed ??
thanks

Hello
I have a big TTL file about (2GB), I try upload it in virtuoso via ISQL:
DB.DBA.TTLP_MT (file_to_string_output ('C:/Program Files/OpenLink
Software/Virtuoso 7.2/vad/geneDiseaseAssociation.ttl'), '', '
http://localhost:8890/ontologies/DisGen');
is this right, or wrong?
I need fastest way, and wish to see a progress bar to know how remaining
time
note:
while it executing, I made COUNT(*) via SPARQL to see if count of added
triples to graph increase or not, I think after 1 hour not add any triple
on graph and ISQL still busy :(

Re: [Virtuoso-users] uploade TTl big file?
I have split my file to 4 files, and Now I'm trying bulk loader strategy,
I see after create the loader, I can see the files handled
select * from DB.DBA.load_list;
the first time was an error in my files, how can I try again run loader
and check status in DB.DBA.load_list (delete last result)??
thanks

[Virtuoso-users] How I make an inference in Virtuoso?
Hi Suppose I have an ontology for fruits: Bana is Fruit. Apple is Fruit. Also suppose I have other dataset that contains: Bassam eat Apple. Husam eat Banana. Can I do following question (SPARQL query) using Virtuoso, Who eat Fruits? the answer must be Bassam and Husam, because there is an inference (Banana and Apple are fruits) Thanks -- --- > Eng.Bassam Najeeb. >Software Engineer. -- ___ Virtuoso-users mailing list Virtuoso-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/virtuoso-users
Re: [Virtuoso-users] Load MySQL database into Virtuoso server
As I know, to able to load a DB into a Virtuoso directly via database tab, the Virtuoso must be a commercial edition. On Mon, Jan 16, 2017 at 4:39 PM, AA Saa wrote: > Hi, > > I am new to Virtuoso.

[Virtuoso-users] Mapping XML files to RDF graph using Virtuoso?
Hi I transformed an SQL database to RDF graph using an R2RML in a commercial edition of Virtuoso 7.2. Now I have 5000 *standard XML files*, Can I do a mapping to RDF Graph "same as R2RML" for those XML files using a Virtuoso???

Re: [Virtuoso-users] Mapping XML files to RDF graph using Virtuoso?
Thank Kingsley Could you please support me more information about 2 fundementals that you has said ??? may be short example :) ?? 1. I think first create an ontology data model for my native XML files. 2. The second step is create a data model mapping between my XML file and an ontology data model which created in the first step "as R2RML does RDB2RDF mapping". Thanks again.
