The DataNamespace is interesting. It is already possible to just add
tabular data to MediaWikis and render them using one of the tabular
rendering extensions. I am using the SimpleTable extension on the Brede
Wiki. I use LibreOffice Calc to edit the data, but on-wiki table editing
and flexible formatting would be preferable. Computation and
visualization of the data from the wiki is done with an off-wiki web
service, see, e.g.,
http://neuro.imm.dtu.dk/cgi-bin/brede_bw_metaanalysis?title=Major+Depressiv…
I have added the following to the state-of-the-art section on meta:
* In the [
http://neuro.imm.dtu.dk/wiki/Main_Page Brede Wiki], Finn Årup
Nielsen is using ordinary namespace pages to store comma-separated
values including one-row header for scientific data, see, e.g.,
[
http://neuro.imm.dtu.dk/wiki/Bipolar_Disorder_Neuroimaging_Database_-_Amygd…
Example on CSV file]. This data can then be transcluded on other pages
on the wiki, see, e.g.,
[
http://neuro.imm.dtu.dk/wiki/Bipolar_Disorder_Neuroimaging_Database_-_Amygd…
example]. The transclusion uses the 'tab' tag from the 'SimpleTable'
extension of Johan the Ghost defined in a template, making a static
table rendering (except for the standard sortable style). The data from
the CSV pages is read by an external script that performs meta-analysis
on the data, see, e.g.,
[
http://neuro.imm.dtu.dk/cgi-bin/brede_bw_metaanalysis?title=Bipolar+Disorde…
meta-analysis example]. This script also allows for export of the CSV
data in JSON format. The 'semantic' annotation of the column header
takes place in standard MediaWiki templates, that are aware of the
format of the external script API, see, e.g.,
[
http://neuro.imm.dtu.dk/wiki/Template:Metaanalysis_csv metaanalysis csv
template] referenced from
[
http://neuro.imm.dtu.dk/wiki/BiND#Meta-analysis BiND metaanalysis
section]. This simple approach, which requires no modification of a
standard installation of MediaWiki beyond the 'SimpleTable' extension
enabling, has been described in more detail in a few articles:

I'd like to hear from the people on this list on a
proposal to create
a dedicated namespace to host open (tabular) data and make these
datasets persistently identifiable, version controlled and easily
embeddable into other wikis.
While this use case is currently not within the scope of Wikidata
(and could potentially live on other Wikimedia wikis, like Meta or
Commons), I'd appreciate input from the wikidata community on this
draft:
