Top Art Looting Investigation Unit Red List Names (by Frequency)

FOLD3: digitized from the NARA microfilm publication, M1782
https://www.fold3.com/title/631/wwii-oss-art-looting-investigation-reports/description
In 1946 the OSS Art Looting Investigation Unit published its Final Report. The Report was accompanied by an Index of Names and a summary of findings called the Red Flag List of Names.

The Red Flag List of Names, while not exhaustive, is extremely interesting for network analysis because of its prosopographical approach, A name could be mentioned more more than a hundred times, with extensive links to others, or only once, with a couple of links.
The document was classified and basically unavailable for many years.

But today, nearly twenty years after the  Washington Conference Principles on Nazi-Confiscated Art, what is known of these Red Flag names?
How are they reflected in authority files?

Publishing open linked data: Tableminer and Austrian data portals

In this interesting paper, Tomas Knap looks at using Tableminer+ to help transform CSV files from Austrian data portals,  http://www.data.gv.at and http://www.opendataportal.at, into Linked Open Data.

Quote
"To leverage CSV files to Linked Data3 , it is necessary to 1) classify CSV columns based on its content and context against existing knowledge bases 2) assign RDF terms (HTTP URLs, blank nodes and literals) to the particular cell values according to Linked Data principles (HTTP URL identifiers may be reused from one of the existing knowledge bases), 3) discover relations between columns based on the evidence for the relations in the existing knowledge bases, and 4) convert CSV data to RDF data properly using data types, language tags, well-known Linked Data vocabularies, etc" -
