SemanGit is the first collection of linked data extracted from <b>GitHub</b> based on a <b>git</b> ontology we designed and extended to include specific <b>GitHub</b> features.
Here we provide this ontology for a semantic representation of the git-protocol and its derviates (Github, Bitbucket etc.) and a cummultative turtle-datasets of publicly accessible data on Github.
Technical documentation on the scripts can be obtained from <b><a href="https://github.com/SemanGit/SemanGit"> Github Project Page </a></b>. A short introduction to the Ontology can be found under the heading <b><a href="#ontology"> Ontology </a></b>.

<hr style="width:50px;border:5px solid blue-grey" class="w3-round">
<p> As a first step, we have created
an ontology for Git and extended it to also take the social features of GitHub
into account. An interactive visualization of our ontology can be found on <a href="http://visualdataweb.de/webvowl/#opts=doc=0;editorMode=true;#iri=https://raw.githubusercontent.com/SemanGit/SemanGit/master/Documentation/ontology/semangitontology.ttl"> WebVOWL </a>. Due to limitations of type setting the underlying ontology is not entirely correclty typed. A full and correct version can be obtained from <a href="https://github.com/SemanGit/SemanGit/blob/master/Documentation/ontology/semangitontology.ttl">GitHub</a>. </p>

<hr>
<p>Due to the fact that we grab all our data from <a href="http://www.ghtorrent.org"> GHTorrent </a> , we have decided
to take their structure into account when developing our ontology. All relevant information provided by them
has been included in our structure, too.
We have ensured to clearly distinguish between Git properties and properties
that do not belong to the Git protocol, but which are provided by GitHub. In
this case, we have created a subclass that can hold all the additional information
and make the basic Git class superclass of it. As an example, a "Git user"
only consists of an email address. That is to say, when creating a commit, one
can specify the author of the commit by providing an email address.
A GitHub user on the other hand is a lot more complex. It has a nickname,
avatar, a creation date, a location etc. So in our ontology, there is a class called
User which only has the user email data field, and a github user subclass that
has 9 more fields, including those mentioned above.
On GitHub, users can leave comments on commits, pull requests and on reported
issues. Seeing that those are very similar, we have grouped those three
classes as commentable, such that a comment can be made for any class that
is subclass of commentable.
Our ontology comprises of 22 classes and 80 properties. During the creation
process, we used the <a href="http://vowl.visualdataweb.org/webvowl.html"> WebVOWL editor tool </a> for building the ontology and
the <a href="http://oops.linkeddata.es/"> OOPS! OntOlogy Pitfall Scanner! </a> for checking the integrity of it. </p>

<!-- Notes on the Dataset -->
<div class="w3-container" id="notes" style="margin-top:75px">
<h1 class="w3-xxxlarge w3-text-blue-grey"><b>Notes on the Dataset</b></h1>
<hr> Our datasets are provided as a Resource Description Framework in the turtle format, with a size of around 400GB for each single dump and around 20.000.000.000 stored rdf triples. To achieve a maximum compression rate, we optimzed our data by choosing prefixes of the length of at most 2 chars, and reencoded all integers into a Base 64 like representation.
<br>
<code>
<br>
# Unoptimized Data<br>
semangit:ghissue_123456 a semangit:github_issue;<br>
semangit:github_issue_created_at "2002-05-30T09:00:00"^^xsd:dateTime;<br>
