wikidata + mediawiki = wikidata + provenance == wikiprov

Today I want to showcase a Wikidata proof of concept that I developed as part of my work integrating Siegfried and Wikidata.

That work is wikiprov a utility to augment Wikidata results in JSON with the Wikidata revision history.

For siegfried it means that we can showcase the source of the results being returned by an identification without having to go directly back to Wikidata, this might mean more exposure for individuals contributing to Wikidata. We also provide access to a standard permalink where records contributing to a format identification are fixed at their last edit. Because Wikidata is more mutable than a resource like PRONOM this gives us the best chance of understanding differences in results if we are comparing siegfried+Wikidata results side-by-side.

I am interested to hear your thoughts on the results of the work. Lets go into more detail below.

Color Theory: What’s the deal with the palettes I’m using?

Following a recent conversation, I wanted to write this blog to add some final pieces of context to my current interest in color palettes.

Binary Numbers

The Binary Numbers project was changed earlier this year following Trump’s inauguration. The original was inspired by simple musings on Data as Art. It was updated again in 2014 after the work had stalled due to technical reasons. I increased the complexity of the images, and incorporated Heritage Color Palettes.

But the end of last year and the beginning of this were exhausting. Two months were spent in protest:

But it seems that this alone was not able to tear the wheels off a tanker in Tienanmen Square… and so I decided on something uplifting. For myself, and for the viewer.

Cinema Palettes was a fantastic Twitter account that takes a scene (not necessarily iconic) from a film and analyses the scene’s colors, presenting back to us, the palette used.

I had been following it for a while and I became curious as to what I might be able to do with it in the configuration of my Binary Numbers.

And so from January this year I adapted the Cinema Palettes concept into this work starting with 50 new color palettes.

The Painter Goblin: Part 4, Putting it all together…

Following the previous posts, bringing this all together meant three different applications.

  • paintergoblin.py – creates the images, can be run standalone
  • wikigoblin.py – retrieves data to tweet from the Wikidata SPARQL services
  • twittergoblin.py – tweets for us! Either a random Wikidata image or from am existing Wikidata link

We create Tweetable information using the wikigoblin. We perform the Tweet using twittergoblin. In between the paintergoblin has to create his art!

We’ve seen examples of the images from the original zine.

Persistence of Memory

How do we turn this concept into something real, and automated?

The Painter Goblin: Part 3, Data Sources

One thing that held the Painter Goblin project back was finding a data source to get images from.

There are potentially hundreds of sources out there, but! The path of least resistance means that:

  • Any source needs either hackable URIs** (uniform resource identifier) or a randomizing function.
  • Ideally, a data source doesn’t link to yet-another-page, e.g. portal like websites to other’s collections.
  • Ideally the data source links directly to an image to download.
  • Data can be easily selected by category, e.g. just paintings, or posters, not just ‘art’.

** A hackable URI is a URI pattern that can be cycled through using computational techniques, even if the underlying data isn’t entirely well-known. E,g, http://example.com/image/0001, http://example.com/image/0002, for subsequent pages, for lack of a more concrete example.

I wanted to explore heritage sources such as Europeana, TROVE, DPLA. I struggled to search these effectively though, and struggled to see how I might automate using them. I recognise they have APIs. I’ll revisit them in the future as I look to expand the Painter Goblin’s corpus.

Enter Wikidata.

Architecture of The-FR.org

Architecture of The-FR.org

Last week I blogged about the publication of a new linked data format registry based on the work I did previously at The National Archives, UK.

Where the work goes, we will have to see. Open sourcing it was an important goal of the short sprint. Partly because I hope it demonstrates an architecture that can be adopted for a similar registry, and it may also provide a code-base that can be adapted for similar, linked open data projects. This blog provides an overview of that architecture…

Data as Art – Data as Culture

Having just typed the original title of this blog post ‘Data as Art’ I realize it is probably the millionth blog to share it. A minor modification should help to identify it among the countless others…

This week, as the newly founded Open Data Institute (ODI) embraces data-as-culture I am reminded about a visualization I attempted a short while back – visualizing prime numbers.
