Hi all, I'd like to make some comments about Mark's comments: 1 & 2) I think your first two points are both related to data provenance > and also the importance of expressing assumptions and explicit reference > units (i.e. value per what?) in calculations. Maybe we (DWBP) need to > highlight some real existing examples of best practice use of W3C > Provenance and provide a commentary about why/how that is considered best > practice. Guidelines can be very worthwhile, but sometimes complementing > these with a few real-life existing best practice examples accompanied by a > commentary can help people to get their data into better shape, if they > have an annotated 'role model' example of what we think it should look > like. It can make it much easier for people to understand the guidelines > if they see concrete examples. > + 1 for the idea of providing examples to help people to understand the guidelines. I think this should be done for every best practice. A best practice may be implemented in different ways and examples should be provided for each one of them. > 3) Regarding visualisations, there are some very nice examples of > visualisation mash-ups at http://publicdata.eu/ , some of which also > include details about the source datasets and the frameworks that were > used.

I'm sure > that there are some other good examples we can highlight, to explain the > benefits of mashing up open data sets to help people understand the data > and make more meaningful comparisons. > I also agree that is important to provide information about how datasets were constructed or combined. This kind of feedback is really important to other consumers, but also to the data publiser, who may provide more general information about the usage of a specific dataset or a set of datasets. I think this kind of information may be described by the Data Usage Vocabulary. > 4) Regarding keeping data close to its source, that works but there needs > to be co-ordination at a federal or ideally global level on the appropriate > vocabularies and terms to be used, so that we can do meaningful comparisons > across these datasets provided by local government.

In my opinion the most important is to have common vocabularies to describe data os specific domains. The data itself may be published in distinct formats and tools may be used to perform data transformations when necessary. However, the use of common vocabularies is fundamental or there will be a lot of extra work to identify mappings between distinct vocabularies. This is a classical data integration problem :) kind regards, Bernadette > > 5) Well done for pointing out that data collected / generated at taxpayer > expense should be made available, without seeking to charge for it a second > time! > > Best wishes, > > - Mark > > > > > > > On 24 Jun 2014, at 09:58, Steven Adler <adler1@us.ibm.com> > wrote: > > > 1.
