Re: Tools to integrate (hundreds) of spreadsheets as RDF

Hi Rafael and everyone,

As you say, Anzo (in particular Anzo for Excel) is designed for 
enterprises to curate large numbers of spreadsheets, map them to 
ontologies & to existing RDF instance data, and maintain them as changes 
are made to the spreadsheets or to the data in the spreadsheets. It can 
be used for CSV-style "tabular" spreadsheets and also for arbitrarily 
"human-oriented" spreadsheets. It can be used both in interactive modes 
(where people are opening up and interacting with spreadsheets) and also 
in automated batch modes.

Anzo stores the RDF data from spreadsheets in an RDF database. Anzo 
includes both authenticated and unauthenticated SPARQL endpoints for 
this data; Anzo can also directly publish the data as Linked Data. 
Finally, Anzo gives you several ways to export RDF data from the database.

Anzo is available in several editions:

  * Anzo Express Starter -- includes Anzo for Excel as above for limited
    #s of users; freely available
  * Anzo Express -- includes Anzo for Excel and Anzo on the Web, a
    user-friendly browser-based dashboard tool for visualization,
    searching, and analyzing RDF data
  * Anzo Enterprise -- includes the above in addition to tools to
    connect to data in relational databases, to integrate unstructured
    data from documents, web pages, etc., to run rules and reasoning and
    work flow processes, various server-side and client-side APIs, etc.

/We also make Anzo available for free for academic use. /

If you're interested in learning more about Anzo or trying it out for 
some of these CDC spreadsheets or the HL7/CIMI work or for any other 
purpose, please drop me a note and I'll be happy to help you out.
