Updates to the tinkerpop proposal

+ = Apache Tinkerpop Proposal =
  {{http://www.tinkerpop.com/docs/3.0.0-SNAPSHOT/images/tinkerpop-logo.png}}
  
- === A. Abstract ===
+ == A. Abstract ==
  
  [[http://tinkerpop.com|TinkerPop]] is a graph computing framework written in Java. A [[http://en.wikipedia.org/wiki/Graph_%28mathematics%29|graph]]
is a data structure composed of vertices and edges and is useful for modeling complex domains
with arbitrary relations (edges, links, lines) between entities (vertices, objects, dots).
TinkerPop provides a core API that graph system vendors can implement. There are various types
of graph systems including in-memory graph libraries, OLTP graph databases, and OLAP graph
processors (see [[http://markorodriguez.com/2013/01/09/on-graph-computing/|On Graph Computing]]
for more information). Once the core interfaces are implemented, the underlying graph system
can be queried using the graph traversal language Gremlin and processed with TinkerPop-enabled
algorithms. For many, TinkerPop is seen as the [[http://en.wikipedia.org/wiki/Java_Database_Connectivity|JDBC]]
of the graph computing community.
  
- === B. Proposal ===
+ == B. Proposal ==
  
  TinkerPop was formed in 2009 and is currently in the milestone series of 3.0.0. From the
start, TinkerPop has provided its software open source and free to use for which ever reason
(commercial or otherwise). Initially the license was BSD, but as of TinkerPop3, the license
was changed to Apache2. The TinkerPop team is composed of developers, evangelists, and representatives
from graph system vendors (see [[http://www.tinkerpop.com/docs/3.0.0-SNAPSHOT/#tinkerpop-contributors|TinkerPop
Contributors]] for more information). TinkerPop has done its best to remain vendor agnostic
and works closely with all vendors to ensure that the constructs within TinkerPop are able
to accommodate the requirements of the underlying graph system. To date, 12 "TinkerPop recognized"
graph system vendors provide TinkerPop implementations. We believe that by joining The Apache
Software Foundation, our vendors, users, and contributors will feel more comfortable in terms
of legal protected, in terms of wider-adoption, and in terms of project stability.
  
- === C. Background ===
+ == C. Background ==
  
- TinkerPop was founded in 2009 and has had steady, active development since. Over the years,
the Gremlin query language within TinkerPop has been adopted by various JVM languages and
as such, there exists Gremlin-Groovy, Gremlin-Scala, Gremlin-Clojure, Gremlin-JavaScript,
and the like. In many ways, Gremlin is seen as a traversal style that can be readily adopted
within the programming constructs of the developer's native language --- both on and off the
JVM. TinkerPop is not bound to the JVM in that developers wishing to interact with a TinkerPop-enabled
graph system can leverage Gremlin Server which provides "over the wire" communication as well
as the entry point for non-JVM language bindings. TinkerPop is being used is production graph-based
applications around the world and is only getting better with age.

- === D. Rationale ===
+ == D. Rationale ==
  
  The graph computing space has grown over the years to encompass numerous graph database
and graph processing systems. TinkerPop was created as a unifying framework for interoperability,
language standardization, and data model standardization.  This framework makes it simple
to "plug and play" the back-end graph implementation without affecting the developer's code.
This is analogous to the way in which the JDBC allows users to swap relational databases while
keeping the same programming interface. TinkerPop also brings together OLTP systems (graph
databases) and OLAP systems (graph processors) by providing a single query language (Gremlin)
for executing graph algorithms transparently over either type of system. The seamless support
of single-machine systems and distributed systems provides an identical end-user experience
within the boundaries of the space and time constraints of the underlying graph system.
  
- === E. Initial Goals ===
+ == E. Initial Goals ==
  
- The goal of this proposal is to migrate TinkerPop to The Apache Software Foundation to 1.)
get more exposure to the project and 2.) legally protect the developers and contributors of
TinkerPop.

- === G. Meritocracy ===
+ == G. Meritocracy ==
  
  TinkerPop already has an established community that values meritocracy. Anyone is welcome
to contribute to TinkerPop and voice their opinions/thoughts on the direction of the project.
If an individual provides beneficial pull requests, documentation updates, theoretical ideas,
etc. then they are asked to join TinkerPop as committers. Moreover, TinkerPop is a business
friendly community. It provides a forum where vendors collaborate, via individual representatives,
by contributing ideas, code and content.
+ 
  We believe the values of the community align well with the ASF, and we are willing to adapt
our practices when necessary.

- The [[https://groups.google.com/forum/#!forum/gremlin-users|TinkerPop mailing list]] has
1500+ subscribers with a flow of approximately 10 emails a day. In addition to the initial
committers there are about two dozen folks that have contributed code to the project, and
1/2 of those are from Graph vendors. Note that there are individuals that participate in the
TinkerPop ecosystem by providing language bindings and system implementations. While not contributing
to the core codebase per se, they support TinkerPop via their software and lecture outreach.

  TinkerPop is licensed Apache2. The OLAP reference implementation that distributes with TinkerPop
is based on [[http://hadoop.apache.org|Hadoop]] and [[http://giraph.apache.org|Giraph]]. There
has been a push from vendors and commercial organizations interested in ensuring TinkerPop
has the legal support of a software foundation. We believe The Apache Software Foundation
to be a great home for TinkerPop.
  
- === K. Known Risks & Abandoned projects ===
+ == K. Known Risks & Abandoned projects ==
  
- TinkerPop is currently at TinkerPop 3.0.0.M6. By joining The Apache Software Foundation,
there is a significant amount of code and time that has passed since TinkerPop's inception.
However, we have done our best to secure CLAs from contributors and to date, have not been
involved in any legal or political issues. TinkerPop has 12 official graph vendors that maintain
or support a TinkerPop implementation for their system. If, lets say, 75% of those vendors
decide against providing a TinkerPop interface, then this would be detrimental to TinkerPop's
efforts. With that, it is very important that TinkerPop remain neutral and engaged with vendors.

lists. We pride ourselves in professional software, documentation, and aesthetics. With its
integration to numerous graph systems in the market, we see TinkerPop as a masterpiece in
a open source technology --- working with both open source and commercial entities to ensure
a solid, respected product.

- TinkerPop is interested in The Apache Software Foundation for the legal support and protection
it can offer our developers. Numerous large software organizations have urged TinkerPop to
join a foundation so that they may more easily provide contributors from their organization
and moreover, maintain confidence in building products atop TinkerPop. With that said, TinkerPop
does respect The Apache Software Foundation brand and believes that by joining The Apache
Software Foundation, we will further boost the recognition and prestige of our product. Finally,
note that a [[http://www.tinkerpopbook.com/|TinkerPop book]] is slated for 2015. Combining
The Apache Software Foundation and a long awaited book should ensure a new uptake of contributors,
users, vendors, and promoters.

that Apache can do, then we will continue funding the creation of our artwork as we have done
in the past.
