Re: There's No Money in Linked Data

Dear Leigh,

Since your analysis in 2009, I can confirm nothing has significantly 
changed.
We have also made a similar survey [1] at OEG-UPM, this time grouping 
similar licenses (from CC and ODC) and getting analogous results. 
Perhaps the growth of datasets in the public domain is remmarkable.

Regading the methodology, I just checked the asserted metadata in the 
LOD group in datahub, the next step being checking whether the licensing 
terms have also been asserted in the datasets.

Regards,
Víctor

Hi Pascal,

Its good to draw attention to these issues. At ISWC 2009 Tom Heath,
Kaitlin Thaney, Jordan Hatcher and myself ran a workshop a legal and
social issues for data sharing [1, 2]. Key themes from the workshop
were around the importance of clear licensing, norms for attribution,
and including machine-readable license data.

At the time I did a survey of the current state of licensing of the
Linked Data cloud, there's a write-up [3] and diagram [4].

*Looking over your analysis, I don't think the picture has changed**
**considerably since then. We need to work harder to ensure that data is**
**clearly licensed.* But this is a general problem for Open Data, not
just Linked Open Data.

You don't say in your paper how you did the analysis. Did you use the
metadata from the LOD group in datahub? [5]. At the time I had to do
mine manually, but it wouldn't be hard to automate some of this now,
perhaps to create an regularly updated set of indicators.

One criteria that agents might apply when conducting "Follow Your
Nose" consumption of Linked Data is the licensing of the target data,
e.g. ignore links to datasets that are not licensed for your
particular usage.

Cheers,

L.
