Hey,
I have some questions/remarks on the "Complete Datamodel in WON" section
Markus wrote up yesterday:
https://meta.wikimedia.org/wiki/Wikidata/Data_model#Complete_Datamodel_in_W…
There are several things we have not modelled yet, which I'm currently not
going to comment on. For those we did already implement or thought about
implementing, there are a few things that do not match what's written in
this section.
> SiteLanguageCode
All occurrences of this should be replaced by GlobalSiteIdentifier, as it's
NOT a language code.
> ItemDescription := 'ItemDescription(' Item {TitleRecord}
[MultilingualTextValue] [MultilingualTextValue] {Statement} ')'
This is missing the aliases stuff, which would be { UserLanguageCode String
}.
> GeoCoordinatesValue := 'GeoCoordinatesValue(' decimal decimal
decimal ')'
Altitude is probably something we will not have in many cases, so I think
this ought to be optional. Another optional argument would be the globe to
which the coordinates belong. Different globes have different ways of
measuring coordinates, so a specific set of coordinates that is valid on
one might mean something else on another and simply be invalid on a third.
> PropertyDescription := 'PropertyDescription(' Property {TitleRecord}
[MultilingualTextValue] [MultilingualTextValue] ')'
Right now the Property interface is very similar to the Item one, except
that Item has what we're calling sitelinks (in the here discussed WON it's
called TitleRecords), and property does not. That's the first difference.
Copy paste error? Or am I misinterpreting the notation?
As with Item, it's missing the aliases.
Although we have not implemented this yet, the Entity interface implies
that it contains a list of statements. I added this after some discussion
with Denny. As a result, both Items and Properties have a list of
statements. That's the third difference with the WON stuff. Here the
question is if non-Item Entities should have statements or not. There is no
consensus on this within the team yet, so I will start a new thread about
it so we can discuss it in more detail.
Cheers

Hey,
There is some disagreement regarding the interface to access statements in
various entities.
== Current implementation ==
This is not fully implemented yet, but it's what the interface implies will
be done.
Entities contain a list of statements. In other words, all items,
properties and queries can have statements.
Obvious objection: "statements" for properties and queries should not have
associated rank and references. They could just have a list of claims.
Original reason to go with this approach anyway: the alternative is to put
statement handling in Item and add claim handling in either both Property
and Query or in a common base. This would result in duplication and loss of
common interface for the Entities.
== New proposal ==
I think we can accommodate all the concerns listed above as follows:
* All Entities provide access to a list of claims.
* Properties and Queries contain a list of claims.
* Items contain a list of statements to which they provide access both as
list of statements and list of claims. The apparent list of claims would
correspond to a filter on rank=primary followed by a map from statement to
it's claim on the list of statements.
Any objections to implementing it like that?
Cheers

Hello all,
I was wondering, now that Wikidata breaks the assumption that pages
store wikitext, has it been considered that Wikidata concept pages could
actually use schema.org markup? Wikidata could possibly read in data
from other web pages which use schema.org markup, but what about the
Wikidata pages themselves having the markup?

change summary
* Bug fixes and improvements for right-to-left languages
* Updated demo system http://wikidata-test.wikimedia.de/
* The long format (more like the json output format) for wbsetitem API
module is now alive
(http://www.mediawiki.org/wiki/Extension:Wikibase/API#New_long_format)

10th ESWC 2013 -- Semantics and Big Data
May 26-30, 2013, Montpellier, France.
http://2013.eswc-conferences.org/
General Chair:
Philipp Cimiano (Bielefeld University, DE)
Program Chairs
Valentina Presutti (STLab, ISTC-CNR, IT)
Oscar Corcho (UPM, ES)
==== *Call for Papers* ====
ESWC is the premier European-based annual conference for researchers and practitioners in the field of semantic technologies. ESWC is the ideal venue for the discussion of the latest scientific insights and novel applications of semantic technologies.
The leading motto of the 10th edition of ESWC will be "Semantics and Big Data". A crucial challenge that will guide the efforts of many scientific communities in the years to come is the one of making sense of large volumes of heterogeneous and complex data. Application-relevant data often has to be processed in real time and originates from diverse sources such as Linked Data, text and speech, images, videos and sensors, communities and social networks, etc. ESWC, with its focus on semantics, can offer an important contribution to global challenge.
ESWC 2013 will feature nine thematic research tracks (see below) as well as an in-use and industrial track. In line with the motto "Semantics and Big Data", the conference will feature a special track on "Semantic Technologies for Big Data Analytics in Real Time". In order to foster the interaction with other disciplines, this year's edition will also feature a special track on "Cognition and Semantic Web".
For the research and special tracks, we welcome the submission of papers describing theoretical, analytical, methodological, empirical, and application research on semantic technologies. For the In-Use and Industrial track we solicit the submission of papers describing the practical exploitation of semantic technologies in different domains and sectors. Submitted papers should describe original work, present significant results, and provide rigorous, principled, and repeatable evaluation. We strongly encourage and appreciate the submission of papers including links to data sets and other material used for the evaluation as well as to live demos or source code for tool implementations.
Submitted papers will be judged based on originality, awareness of related work, potential impact on the Semantic Web field, technical soundness of the proposed methods, and readability. Each paper will be reviewed by at least three program committee members in addition to one track chair. This year a rebuttal phase has been introduced in order to give authors the opportunity to provide feedback to reviewers' questions. The authors' answers will support reviewers and track chairs in their discussion and in taking final decisions regarding acceptance.
** Important Dates (11:59pm Hawaii Time) **
Abstract submission: December 5th, 2012
Full paper submission: December 12th, 2012

Heya folks :)
We updated the demo system again. The corresponding git tag is:
8a7284ca581c8c6981613335b5e73b9359e856f0
Most important are problably:
* new API for bots (bug 39143)
* lots of rtl testing still needed
The next demo update after this should hopefully give you the first
user-visible parts of phase 2 of Wikidata. \o/
It's getting wet and cold outside here. Perfect time for some hacking
on Wikidata for you? Here's some new stuff to work on:

This survey of bot libraries in several langugages
https://github.com/cariaso/smwcon2012bots
and this semi-functional SMW aware bot
https://github.com/cariaso/Semantic-MediaWiki-Bot
may also be of interest. In time I hope to ensure wikidata is well
supported in these tools.

Heya folks :)
We just updated the demo system again with the newest code so you can
give it some testing. In the process we had to delete the existing
user accounts. Sorry about that.
http://wikidata-test.wikimedia.de
New stuff to try out includes:
* table layout on item pages has been reworked
* edit conflict detection
* undo/restore for edits
Cheers
Lydia
