[Wikidata-l] Mapping Wikidata properties to Freebase properties

[Thad Guidry]

Experiment for tonight:
Figure out how the hell to map 1 of my Freebase base types...to a wikidata
SOMETHING.

https://www.wikidata.org/wiki/Q1427887

is the same as

https://www.freebase.com/base/beefbase/meat_product?schema=

and I noted on Q1427887 that the Freebase identifier is /m/0gxp3zs  GREAT.

Now, how would the https://www.wikidata.org/wiki/Property:P1628 as
mentioned by Tpt_ during the office houractually be used somewhere to
further enhance a connection between the two ?

Help,
Thad

Hi Valentine,

The long, chatty, free-text descriptive element of Wikidata is really
Wikipedia ;-)

There is a small free-text field in Wikidata for each item (the
description, one per language) but it's intended for a short
identifying/disambiguating note: "1887 self-portrait by XYZ"; "Danish
artist and historian, 1912-1974", etc.

Dimensions are, I believe, being worked on.

Andrew.

If people really care we might be able to get around that if we would
simply migrate it to https://github.com/wikidata.

[Joe Filceolaire]

We do have the "Quote" property (P1683) which has monolingual text
datatype. You could certainly put free text in the value for this property
and add this to a reference or even use it as a qualifier.

[Wikidata-l] Initial release of the primary sources tool

[Denny Vrandečić]

I am happy to let you know about the initial release of the primary sources
tool. More info is available here:

https://www.wikidata.org/wiki/Wikidata:Primary_sources_tool

The release is meant to facilitate your feedback. There are probably plenty
of things that should be fixed before the tool gets widely used. Please
report the issues:

https://github.com/google/primarysources/issues

Even better are pull requests!

A huge shoutout to Sebastian Schaffert (backend) and Thomas Steiner
(frontend) who worked on the tool in their 20% time.

Free-form text is not machine-readable. Coding semi-structured information is
very common in archives etc, but makes the data very hard to export, transform,
and query. Free text fields should be used only for things that are actually
text, such as a state motto.

I think the need to encode things in free-form fields arose mostly from overly
rigid data schemas. If there's no dedicated field for something, just stuff the
info into the text field. Such fields turn into kitchen sinks that contain a
hodge podge of different kinds of information.

With Wikidata, there should be no need for this, since you can just create and
use any properties you might be missing. That does mean though that wile
importing, you have to somehow extract the relevant information from the free
text. That effort has to be done at some point, if the data is to become machine
readable.

We don't support units of measurement yet, and without these, it's not really
possible to give the dimension. We hope to finally change this over the next
couple of months.

xml:lang would be used in the XML/RDF export (and lang in the HTML rendering).
Internally, the language would be a string associated with the "language" key in
a JSON structure. But neither fact is really relevant to the data model on an
abstract level.

Most properties (most data types) are language agnostic. Quantities, strings,
time values, etc, do not have any notion of language. The only datatype for
properties that supports a language code is "monolingual text" (a pair of
language code + text). This data type is used sparingly, since usually, the need
for internationalized naming and description is covered by the labels,
descriptions, and aliases associated with a data item.

Labels, descriptions, and aliases are not "properties" about which (sourced)
statements would be made in the context of the data item. Instead, they are
editorial attributes. They are fully internationalized, and intended to enable
display, disambiguation, and search in as many languages as possible.

For example, Q219831 has labels (and descriptions) in many languages:
* nl: De Nachtwacht  (schilderij van Rembrandt van Rijn)
* de: Die Nachtwache  (Gemälde von Rembrandt)
* en: The Night Watch  (painting by Rembrandt van Rijn)
* ru: Ночной дозор  (картина)

So, when the painting is referenced elsewhere, a label (and description) can be
shown in the user's language. Internationalized statements/properties are rarely
needed.

[Wikidata-l] Data templates

[Valentine Charles]

Dear all,

Thank you all for your answers. I will have a look to the different
projects you have mentioned in your emails.
In the meantime I have spent a bit more time exploring Wikidata for
paintings as one of our project currently focuses on Art and comparing it
with the Europeana Data Model in terms of properties. I have noticed the
absence of some properties and I would be curious whether it is just an
overlook or whether there is a real intention behind the omission:

-Cultural Heritage data have most of the time a description property where
you will find lot of relevant free text information. The structured
property but inside you will find mostly free- text. I couldn't find a
similar property in Wikidata but there is something similar in Dbpedia. Is
it something you are planning to introduce or have you made the decision to
exclude any free-text infromation from Wikidata for now.

-While I was looking for painting in Wikidata I also noticed the absence of
information related to the size/dimension of the Artwork. The information
is most of the time present in Cultural Heritage data. Is it something
Wikidata is interested in or has it been omitted intentionally?

-Then the last question is about values in different languages for a given
property. How do you indicate the language in Wikidata? Are you using a
xml:lang attribute or something similar?

Thank you very much for your help

Best,

Valentine
