Hi Wikidata community,
Kadaster, the Dutch cadastre agency is publishing its base registries as
Linked Open Data. This means that we have minted unique identifiers for
all buildings, roads, etc in the Netherlands.
Wikidata currently includes links to the Kadaster, but these do not point
to the proper IRIs. For example, Dutch municipalities in Wikidata
currently link to an HTML viewer of Kadaster [1], but they should point to
our dereferenceable IRI [2].
Low-hanging fruit seems to be to update the Kadaster links for all Dutch
municipalities. What's the best way to go about this? Can we make these
corrections ourselves / what is the procedure for editing?

Cheers!,
Wouter.

[Sorry for cross-posting. I just sent this mail to the Wikicite mailing
list, but I thought it could be of interest also here. Moreover, the
community here could provide some important insight to better explain
wikidata to "newbies" and set the right path for a meaningful conference.]
Dear all,
sorry for the messy email, but I'd like to to express a small concern I
have regarding the awesome Wikicite conference we'll have in few days.
My main point is that Wikidata is *complex*.
It's not just the data model (which is not easy, per se), but the whole
idea behind wikidata, the policies, the community, the workflow, the tools,
and the whole helo of vagueness that sorrounds it.
My favourite example about this is this little story:
https://en.wikipedia.org/wiki/Blind_men_and_an_elephant
(which was actually a very good metaphor used by my professors introducing
the Information Science course...)
Different people with different background work with data in different
manners: the word "data" (as "information") means anything and its
contrary, so we must be careful. You know better than me that everyone
projects her own dreams and delusions upon Wikidata, so we must work
towards a good understanding at the beginning, to avoid the painful and
time-consuming job of making people un-learn things they think they know.
This was quite evident especially last year, when a lot of librarians and
wikimedians were in the same room, and everyone knew many things about
metadata and their metadata model: librarians had difficulties grasping
things about Wikibase, Wikidata, policies and communities, and wikimedians
about bibliographic models and complexities.
We spent at least 30 minutes explaining Wikidata from the beginning, also
adding some "color" about strategies, policies and community.
I'll try to make examples.
* we need to explain that in Wikidata (and Wikibase) everything is an
*item*. Everything. Every items has properties, values, qualifiers. What's
not possible is to have sets or clusters of items, and to give properties
to such sets and clusters. This is somehow related to the book topic.
* we need to explain that there are at least 2 different possible
strategies: create few general properties and many specific items,
or create many specific properties and less general items. Wikidata chose
the former.
* we need to explain the "scaffolding principle", meaning that we don't
need to put *all the info in all the items*. We need to create and organize
items that are *queriable*, in such a way that I can make a query that get
all the data and details I need, scattered among different items. If the
items in questions are built "on top of each other", this is doable. It is
actually very important to understand this, because people get confused
about how many things to say inside one item. This principle (and the
former) was explained to me by Tobias1984, and helped me a lot in my
understanding of Wikidata.
I think that this kind of insight is crucial for working with Wikidata in a
meaningful way, because wikidata offers *one product*, with *one data
model*, and it simply impossible to adapt and stretch the Complexity Of The
World to Wikidata without loss of information.
I'm sure many of you know this perfectly, but other people maybe don't, or
at least they will struggle with it.
We all come from different backgrounds and are emotionally very attached to
our models and our crucial pieces of information we don't want to lose: in
this sensse, Wikidata is much more a "negotiation" than Wikipedia, because
Wikipedia is not structured and llows for much more messiness.
Every model and decision we will make will be a trade-off, and I think it's
worth trying to save time and effort trying to establish these boundaries
at the beginning.
Of course, there are many insights about Wikidata I don't have, but those
are kinda the things we want to understand first in these kind of
conferences.
Hope this makes sense.

Hi everyone!
I am trying to configure Wikibase in a wiki that I have installed. I
want to use both, repository and client. I have followed installation
instructions <https://www.mediawiki.org/wiki/Wikibase/Installation>, but
I think that I made something wrong because now I have several errors in
my wiki.
If I access to any page of the site I see "Internal error", the error
and the backtrace. For example, in the mainpage:
[e837b2d7a6fcc7e1edaead2a] /Portada Error from line 240 of
/[PATH]/extensions/Wikibase/client/includes/Store/Sql/DirectSqlStore.php:
Class 'Wikimedia\Rdbms\SessionConsistentConnectionManager' not found
It also happens when I try to edit any page in main namespace. Then,
another error is when I visit the page Special:CreateItem:
[1d904eb6d5d155e0d0c710ae] /Especial:CreateItem TypeError from line
32 of
/[PATH]/extensions/Wikibase/repo/includes/Store/Sql/SqlIdGenerator.php:
Argument 1 passed to Wikibase\SqlIdGenerator::__construct() must be an
instance of Wikimedia\Rdbms\LoadBalancer, instance of LoadBalancer
given, called
in/[PATH]/extensions/Wikibase/repo/includes/Store/Sql/SqlStore.php on
line 298
You can check my settings for Wikibase in that gist
<https://gist.github.com/distriker/6a387d967a7b48e36f41055f00c3c366>.
But I have made is config both extensions in the same file and the
namespaces like as explain the advanced configuration
<https://www.mediawiki.org/wiki/Extension:Wikibase_Repository#Advanced_Confi…>.
I have configurated PHP 7.
Any idea? Thanks in advance!
Regards, Iván

Subject: [OSM-talk] new Wikidata+OSM data in one RDF database
To: OpenStreetMap talk mailing list <talk(a)openstreetmap.org>
TLDR: A SPARQL (rdf) database with both OSM and Wikidata data is up for
testing. Allows massive cross-referenced queries between two datasets. The
service is a test, and needs a permanent home to stay alive.
Overpass Turbo is awesome, but sadly it does not have data from Wikidata,
nor does it support some SQL-like conditions. I have setup a temporary RDF
database that has both OSM & Wikidata. You can use SPARQL queries to find:
* All OSM objects with wikidata tag that references a Wikipedia
disambiguation page. Get the name of the page in first available language
ru, fr, de, en. http://tinyurl.com/mzlfb26
* OSM relations with wikidata tag pointing to a person (also tries multiple
language fallbacks). http://tinyurl.com/m6fh3wx
* OSM relations with duplicate Wikidata IDs http://tinyurl.com/mvhhogx
== OSM data structure ==
osmnode, osmway, osmrel - OSM object prefix, e.g. osmnode:1234
osmt - tag, e.g. osmt:name:en (only has tags with latin chars, -, _, :,
digits
osmm - meta data about the object -- type, isClosed, version.
I try to preserve OSM data without much changes. Every tag's value is
stored as a string, except for wikidata and wikipedia tags which are
converted to a URL, the same format as stored in Wikidata.
osmway:29453885
osmt:name "Samina";
osmt:waterway "river";
osmt:wikidata wd:Q156065;
osmt:wikipedia <https://de.wikipedia.org/wiki/Samina>;
osmm:type "w"; #### could be "r", "w", and "n"
osmm:isClosed false; #### this meta property is only for OSM ways
osmm:version 24.
Wikidata data structure is identical to https://query.wikidata.org (see
help)
== Current limitations ==
* Only includes OSM objects with either "wikidata" or "wikipedia" tags
* The OSM data only contains tags with only Latin letters, digits and
symbols - : _
* OSM geometry info is not imported, e.g. no center point or bounding box,
except for osmm:isClosed (true/false) property for ways.
* Does not include OSM object inheritance data - e.g. cannot query for
"find a node that is part of a way which is part of a relation that has
wikidata tag that ..."
* Wikidata is updated every second, but OSM does not yet update at all,
imported from a full db dump as of a few days ago.

Hi,
I am studing the viability of use wikidata for store manufactured products
information, this is my project proposal
https://meta.wikimedia.org/wiki/WikiObject.
One of the challenges would be to protect product data like manufacturer
property value or like width, lenght or any tech specs that are defined by
manufacturer at the origin.
After reading Wikipedia:Protection_policy
<https://en.wikipedia.org/wiki/Wikipedia:Protection_policy>, I'm answering
myself if it could be possible to protect only these property values, for
example defining a standart template for them, and make it only editable by
authorized users (manufacturers?)
greetings and thanks in advance
