Hi Bernadette,

Thanks.

Yes. I know DBPedia provides an ontology, but as far as I know, it reuses
some vocabs (e.g. FOAF, Schema.org and Bibo) but few annotations about the
Classes are provided, such as rdfs:label and rdfs:comment. However, nothing
related to metadata describing where came from or how it was derived, and
so on (see first e-mail).

So, I am talking vocabs like DC, Org (perharps aligning with schema.org)
and BIBO (extending the use). But I think the most important is to use a
vocab to foster trust. This is directly connect to the Quality and
Granularity Description Vocabulary (again, see the charter). That's why I
think a use case describing it could be interesting.

Please, let me know if is plausible or not.

All the best,
Ig

>>
>>
>>
>> The first project we heard about came from a local nonprofit called *Tomorrow
>> Lab* <http://tomorrow-lab.com/>, who have designed hardware that
>> measures how many bikes travel on streets they measure.  It uses simple
>> hardware and open source software that connects two sensors with a
>> pneumatic tube that measures impressions for weight and axel distance that
>> differentiates between bikes and cars.  Its called WayCount.  The text
>> below is from their website.  In the room we discussed how WayCount data
>> could be combined with NYPD crash reports to more accurately identify the
>> spots in NYC where bike accidents per bike numbers occur and identify ways
>> to remediate.
>>
>> WayCount is a platform for crowd-sourcing massive amounts of near
>> real-time automobile and bicycle traffic data from a nodal network of
>> inexpensive hardware devices.   For the first time ever, you can gather
>> accurate volume, rate, and speed measurements of automobiles and bicycles,
>> then easily upload and map the information to a central online database.
>>  The WayCount device works like other traffic counters, but has two key
>> differences: lower cost and open data. At 1/5th price of the least
>> expensive comparible product, WayCount is affordable. The WayCount Data
>> Uploader allows you to seamlessly upload and map your latest traffic count
>> data, making it instantly available to anyone online.
>> Collectively, the WayCount user community has the potential to build a
>> rich repository of traffic count data for bike paths, city alley ways,
>> neighborhood streets, and busy boulevards from around the world. With a
>> better understanding of automobile and bicycle ridership patterns, we can
>> inform the design of better cities and towns.
>>
>> The WayCount platform is an important addition to the process of
>> measuring the impact of transportation design, and creating livable streets
>> by adding bicycle lanes, public spaces, and developing smart transportation
>> management systems. By creating open-data, we can increase governmental
>> transparency, and provide constituencies with the essential data they need
>> to advocate for rational and necessary improvements to the design,
>> maintenance, and policy of transportation systems.
>>
>> The hardware and software of the WayCount device and website were
>> designed and engineered by Tomorrow Lab.
>>
>> WayCount devices are currently for sale on the website, *WayCount.com*<http://waycount.com/>
>>
>>
>>
>>
>>
>> We also discussed some ideas to provide policy makers with better sources
>> of Open Data to guide policy discussions, and then broke up into four
>> groups focusing on different projects.  One group discussed how to save the
>> New York Library on 42nd Street from the imminent transformation of its
>> main reading room and function as a lending library.  Another group scraped
>> web pages for NYPD crash data for an app comparing accident rates across
>> the 5 boroughs.  Some people just spent time talking about who they are and
>> what they want to work on, what they want to learn, and how to get more
>> involved.
>>
>> I spent an hour with a young programmer who had worked on the NYC
>> Property Tax Map I shared with you last week.  He showed me a Chrome Plugin
>> he is working on that provides data about leading politicians whenever
>> their names are mentioned on a webpage.  It is called Data Explorer for US
>> Politics and it provides some nifty data on things like campaign
>> contributions compared to committee assignments.
>>
>>
>>
>> I asked him where he got his data and he showed me *DBpedia*<http://dbpedia.org/About>,
>> which "is a crowd-sourced community effort to extract structured
>> information from *Wikipedia* <http://wikipedia.org/> and make this
>> information available on the Web. DBpedia allows you to ask sophisticated

>> huge amount of information in Wikipedia to be used in some new interesting
>> ways. Furthermore, it might inspire new mechanisms for navigating, linking,
>> and improving the encyclopedia itself. "
>>
>> Then I asked him how he knows that DBpedia data is accurate and reliable
>> and he just looked at me.  "It's on the internet..."  Yeah, and so where
>> weapons of mass destruction in Iraq.  But they were only on the internet
>> and never in Iraq.  And herein lies a huge problem about Open Data on the
>> Web; there is no corroboration of fact, no metadata describing where it

>> its veracity, yet we all use it on faith which just ain't good enough.
>>
>> This is why we have the *W3C Data on the Web Best Practices Working
>> Group* <https://www.w3.org/2013/dwbp/wiki/Main_Page> - to create new
>> vocabulary and metadata standards that attach citations and lineage,
>> attestations and data quality metrics to Open Data so that everyone can
>> understand where it came from, how much to trust it, and even how to
>> improve it.
>>
>> At the end of the evening, we also discussed IBM Smarter Cities, the
>> Portland System Dynamics Demo, and the possibility of hosting a BetaNYC
>> meetup at IBM on 590 Madison Avenue.  It was a fascinating evening and I
>> encourage all to check out the links provided in this writeup and get out
