Hi Marios, 

I just want to make a clarification. 

The IHU browser is actually getting data from the public SPARQL endpoint 
available at: http://linkeddata.ihu.edu.gr/sparql and not from 

This also explains why Kostas gets different responses when looking up his 
organisation in IHU and in publicspending.gr both in terms of description 
metadata and different URIs. 

However, as Kostas correctly points out, we have made sure that the legal 
entities of IHU are linked to the publicspending.gr ones. 

We have also created a SKOS taxonomy of company types in Greece which 
provides values to rov:companyType. 
The taxonomy was created bottom-up by analysing and reconciling data found 
in the 28000 descriptions of entities used in the pilot application. 
It therefore represents quite accurately the current state of play in 

Effectively, "那滔由 招茄庞闪@gr" is not just a literal. It actually 
corresponds to the prefLabel of a  skos:Concept. 
In case there are additional questions and/or feedback on the pilot (which 
is always welcome), please contact me and/or Natasa Varitimou (cc'ed), who 
has been the lead developer. 

Kind regards,

Thanks for that. Actually, I do know that your work is 'feeding' IHU!!!

I still have a problem though. I'd like to describe it with an example
however: I am searching for the rdf data related to my organization, i.e.
North Aegean Region Administrative Authority (NARAA) "信焉峙雅闪 孪雅上
辽昧上' in Greek, and I get the following 2 responses for both sparql
services respectively:

1. http://publicspending.medialab.ntua.gr/describe/paymentAgents/090344143

2. http://linkeddata.ihu.edu.gr/id/company/090344143 (IHU)

As expected, there is a sameAs property relating these entities (defined 
IHU dataset). But in (1), the entity is described as "那滔由 招茄庞闪" 
the property psgr:legalStatus, and in (2) the entity is described as "
那滔由 招茄庞闪@gr" using the property
http://www.w3.org/ns/regorg#companyType. In addition, you now introduce a
new term to characterize organizations in Greece, using the uri

ty (label "Public Legal Entity", which I guess it comes from your own 
vocabulary (which you say it is a profile of ORG). 

The question is, give all these three different ways to describe the type 
my organization, i.e. a 'Greek public formal legal organization', which
namespace will be the most appropriate? I feel that re-using REGORG
namespace is a more appropriate practice, don't you?

Anyways, for me now it is a matter of linking our dataset with one of the
two datasets (IHU or NTUA), since NARAA entity is already defined in the
LOGD (twice).

Dear Kostas,

     the data from the IHU browser is actually drawn from the sparql
endpoint at http://publicspending.medialab.ntua.gr/ .
The IHU project uses the string descriptions taken from the greek taxation
service (TAXIS), but there is no actual standardization or schema involved
and sometimes the strings have overlapping meanings and even typos.
In the publicspending.gr project we have actually deployed a small 
for greek organizations as a profile of ORG, having in mind future 
to foreign classification schemata.
You can see the legal entity types here
http://publicspending.medialab.ntua.gr/en/endpoint , selecting the
predefined query "Categorization of legal entities" from the example 

Kind regards,
Marios Meimaris
