Possible Data APIs

There are a number of possible data APIs that might be of interest.

Google Books API

• We can use this API to search for books or authors and retrieve data (e.g. ISBN, title, author, publish date)
• Data is retrieved through 'volume IDs' which books have - authors don't have IDs
• How this data can be represented as a graph is problematic though - this data source will probably end up like TMDB, with the use of IDs rather than a graph

OpenStreetMap API

• There is an example that was made for #77 with graphs of the Melbourne area
• It is also be possible to load data dynamically though, for example, loading a region with a bounding box into the graph
• This might be worth investigating

GitHub API

• Possibilities include:
  • Generating a tree to represent forks of a repository
  • Generating a tree to represent the file structure of a repository
  • Generating a graph to represent followers of users

A Hyperlink Graph

• Would be useful for PageRank, and hyperlink graphs are intuitive graph representations (in my opinion)
• Possible data sources:
  • http://webdatacommons.org/hyperlinkgraph/
  • https://snap.stanford.edu/data/web-Google.html
  • http://law.di.unimi.it/datasets.php)
• We'd probably have to take a small slice of these graphs because these have hundreds of thousands of nodes

For the Google Books API, we have agreed on the following method:

get_book_info(search terms) -> list of dict  (incl ISBN, author, title, date, publisher)
