5. Nice…but You should point to related, complementary collections
Otherwise Thesaurusportal will stay an isolated application
You should distribute it as a database for further use
You should add a license
And always remember: There is no such thing as a central point or one-stop-shop on the Web

8. Still nice…but
Given the list of related collections and similar existing registries, the role of BARTOC is not clear
The range of structured vocabularies from simple authority files to ontologies is quite large, so there is a risk of arbitrariness
It is unclear how BARTOC differs from existing collections
There seems to be no automatic integration of data from existing registries to avoid duplication, nor methods to export the registry data as RDF, via OAI and/or by data dumps for aggregation and reuse by third parties
Up to now, BARTOC is kind of a data silo that should be avoided by Linked Open Data
On the other hand, a large collection such as promised by BARTOC would be very helpful for knowledge organization
In summary, the project is very promising, but not mature enough

12. From basic to full terminology registry
Basic terminology registries Full terminology registries
“contain only the metadata of KOS vocabularies” “contain also the members (e.g., concepts, terms, relationships) of the vocabularies”

14. Virtuoso RDF Triple Store Search interface for concepts
Current state
Drupal CMS
(bartoc.org)
Metadata of ~ 2,700 vocabularies & 83 terminology registries
EuroVoc subject headings, DDC & ILC notations/captions
Free database download (PDDL 1.0) in xml, csv, doc, txt, xls & json
RDF mappings to NKOS AP & ADMS
Each record can be retrieved in RDFa as Linked Open Data
Already 150 vocabularies in SKOS format = browsable
JSKOS dumps
Virtuoso RDF Triple Store
SKOS file upload
RDF encoding of BARTOC data
JSKOS is a unified format for information about knowledge organization systems, based on SKOS and JSON-LD
Data can be used as public domain (CC0)
RDF/SKOS concepts
Visualized vocabularies
Search interface for concepts
Wikipedia articles of KOSs
Node URIs
Wikidata
Skosmos (?)
224 entities already have BARTOC IDs
261 Wikipedia articles are linked to BARTOC

15. Nice…but
BARTOC is kind of a data silo that should be avoided by Linked Open Data
no longer
