PhyloPic Week 2: Lineages, Browsing, and API

Another good week for PhyloPic. There are now well over 200 silhouettes in the database. I also rolled out some new features and enhancements.

Redesigned Lineage Pages

Lineage pages now provide taxonomic and license information for each image. As a visual touch, figures now fade as they go deeper and deeper into the past. Here's a few of my favorite lineage pages so far:

• Anhanguera santanae (pterosaur)
• Catocala nupta (moth)
• Corvus corax (avian theropod dinosaur)
  
• Damon johnstonii (whip spider)
  
• Giraffatitan brancai (sauropod dinosaur)
• Homo sapiens sapiens (primate)
• Pantodon buccholzi (butterflyfish)
• Therizinosaurus cheloniformis (theropod dinosaur)

Yes, they're all bilaterian animals. There's a definite bias.

Image Browser

Now you can peruse the entire gallery much more easily, with the Image Browser. Use the arrow(s) on the side to navigate through pages of silhouettes.

Developer API

For any developers out there who want to use the PhyloPic database to create their own apps, now you can. I've provided an initial API, available both as a JSON service and an AMF service for Flex apps.

Also of news to developers: I've opened up the code base for viewing and cloning. (Still need to add the licenses, though.) It's a Django app, written in Python. Feel free to poke around.

Thanks

I'd like to thank everyone who's submitted images so far, especially FunkMonk, Scott Hartman, Matt Martyniuk and Maija Karala for their many contributions. (Each of them has submitted at least a dozen.) Thanks also to Steven Coombs, Craig Dylke, Mo Hassan, Neil Kelley, Dann Pigdon, Ville-Veikko Sinkkonen, Patrick Strutzenberger, Reka Szabo, David Tana, Michael P. Taylor, and Emily Willoughby!

pymathema, a Python tool for evaluating MathML

Lately I've been learning the programming language Python, and I've really been enjoying it. In particular, as a dynamic language (i.e., having loose types), it's really well-suited for mathematical tools. (Having sets and tuples as native types doesn't hurt, either.)

I started creating a MathML-Content evaluator in Python, with an extension for Names on Nodes which implements phyloreferencing expressions. As part of this I am working on Version 2.0 of the Names on Nodes MathML Definitions, which will expand upon the current ones.

Basic functionality is pretty much complete, although there are some niceties to add. If you'd like to check it out and maybe collaborate, have a look here: PYMATHEMA.
