Mining GitHub – Followers in Tinkerpop

Patrick Wagstrom writes:

Development of any moderately complex software package is a social process. Even if a project is developed entirely by a single person, there is still a social component that consists of all of the people who use the software, file bugs, and provide recommendations for enhancements. This social aspect is one of the driving forces behind the proliferation of social software development sites such as GitHub, SourceForge, Google Code, and BitBucket.

These sites combine together a variety of tools that are common for software development such as version control, bug trackers, mailing lists, release management, project planning, and wikis. In addition, some of these have more social aspects that allow you find and follow individual developers or watch particular projects. In this post I’m going to show you how we can use some this information to gain insight into a software development community, specifically the community around the Tinkerpop stack of tools for graph databases.

GitHub as a social community. Who knew? ;-)

Very instructive walk through Gremlin, GraphML, and R with a prepared data set. It doesn’t get much better than this!

GraphML Specification

GraphML Specification

GraphML is a comprehensive and easy-to-use file format for graphs. It consists of a language core to describe the structural properties of a graph and a flexible extension mechanism to add application-specific data. Its main features include support of

  • directed, undirected, and mixed graphs,
  • hypergraphs,
  • hierarchical graphs,
  • graphical representations,
  • references to external data,
  • application-specific attribute data, and
  • light-weight parsers.

Unlike many other file formats for graphs, GraphML does not use a custom syntax. Instead, it is based on XML and hence ideally suited as a common denominator for all kinds of services generating, archiving, or processing graphs.

Interchange syntax for graphs in XML.

GraphML Primer

Abstract:

GraphML Primer is a non-normative document intended to provide an easily readable description of the GraphML facilities, and is oriented towards quickly understanding how to create GraphML documents. This primer describes the language features through examples which are complemented by references to normative texts.

Nice introduction to GraphML.
