when you say "wikidata is not well suited for lists data", you refer
to wikibase or WDQS here?
the
data:Bea.gov/GDP by state.tab above is certainly a good
representation for efficient delivery (via json) and display of data.
but inefficient for further data sharing without URIs.

There is a better alternative to storing lists -
https://www.mediawiki.org/wiki/Help:Tabular_Data -- it allows you to store a
CSV-like table of data on Commons, with localized columns, and access it
from all other wikis from the <graph> and Lua scripts.
A good example of it -- "per state GDP" page -- see graph in the upper
right corner.
Page: List_of_U.S._states_by_GDP
Data: GDP_by_state.tab
Wikidata is not very well suited for lists data, but tabular data was
designed for a relatively large (up to 2mb) lists.

great I will be on site as well, so we will have a little more time to

Hi Marco,
I agree that many of these lists and tables could be harvested (with
some care, of course).
However, I don't think that the information they contain should go to
the Wikidata item they are associated with. This Wikidata item mostly
exists to store inter-language links, but is poorly connected to the
rest of the knowledge graph. This tax revenue and GDP information should
go to the country items themselves.
I am working on the problem of extraction of statements from lists and
tables and will write a tutorial when the tools are ready. WikidataCon
attendees might have a glimpse of that in this session:

I have noticed a lack of actual data in wikidata
representations of
wikipedia list.
for example
List of countries by tax revenue to GDP ratio
https://en.wikipedia.org/wiki/List_of_countries_by_tax_revenue_to_GDP_ratio
to
List of countries by tax revenue as percentage of GDP (Q2529105)
https://www.wikidata.org/wiki/Q2529105
is there currently a development in the wikidata community to
transform these lists into wikibase items and last but not least
produce RDF respresentations for WDQS?
best,
Marco
