#Wikidata - Sembiyan Mahadevi - is it a title or is she a queen?

Queen Sembiyan Mahadevi was the spouse of  Gandaraditya, her son was Uttama Chola. Many of the Chola queens who followed her used "Sembiyan Mahadevi" as a title. This is what the English article tells us.

To really accept that it was a title, a source would help. It would be cool to have a list of all the people who used the title and it would be good to separate the person from the title in separate articles. It seems that the Tamil article is more substantial but as I do not read Tamil and Google translate does not help me sufficiently to understand what it says. 

Queen Sembiyan Mahadevi matters not only because she is important in the Chola dynasty but also because of the relevance she has in Tamil culture. Her father was a Mazhavarayar chieftain but Wikipedia does not know about them. 

When Wikidata knows about Indian nobility, its dates and connections, it becomes a resource that is helpful. Once her father has a name and it is clear what is meant by a "Mazhavarayar chieftain", slowly but surely it becomes clear who ruled where and who were contemporaries. It would be cool when Wikidata allows for a query that shows a "monarch" and shows fellow monarchs in neighbouring countries.

#Wikimania - What have we learned, how to experience it

We have not all been to Esino Lario. It is where Wikimania 2016 happened. That does not mean that it is not possible to see many of the presentations. You may find them on YouTube, maybe elsewhere. The same goes for presentations of previous Wikimania's.

In the history of Wikipedia and our movement, these presentations are notable. It even makes the people who presented notable. As I have been watching several presentations, as I argued that we are really bad at recognising our own notability, I have created a list; they link to lists of presentations for previous Wikimania's. The cool thing is that they are updated regularly by the ListeriaBot. So when I or someone else adds a Wikimania talk, the talk will magically appear.

What you find is rather basic but it works. You will be linked to the presentation on YouTube, You will be linked to the items for the "author", the language used for the presentation and the talk itself. At this stage Wikidata like Commons is mostly a repository. For best effect use Reasonator. Compare Wikidata with Reasonator for the presentation of James Heilman for instance..

I am really happy to have been helped by TweetsFactsAndQueries. He helped a lot in getting the SPARQL queries in a reasonable shape. He figured out how to show only the YouTube video ID instead of the full URL. It is probably possible to show an icon instead but that is for later. What is missing are links to the presentation (the power point) and the submission paper. I have no idea yet how that is to be modelled in Wikidata.

It is important to include such data for several reasons. First it brings access to the presentations for the people who are interested. Secondly it documents what we do puts a timestamp to our thinking in time. Thirdly it documents our history.
