Hello everyone, Over the last 2 weeks, TinkerPop's proposal has been worked on with support from: * David Nalley (champion) * Rich Bowen (mentor) * Hadrian Zbarcea (mentor) * Daniel Gruno (mentor) * Marko Rodriguez (submitting on behalf of TinkerPop) We feel it is now in prime shape from submission to vote. Enjoy!. (URL to wiki version: https://wiki.apache.org/incubator/TinkerPopProposal) A. Abstract TinkerPop <http://tinkerpop.com/> is a graph computing framework written in Java. A graph <http://en.wikipedia.org/wiki/Graph_%28mathematics%29> 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 <https://wiki.apache.org/incubator/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 On Graph Computing <http://markorodriguez.com/2013/01/09/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 withTinkerPop <https://wiki.apache.org/incubator/TinkerPop>-enabled algorithms. For many, TinkerPop <https://wiki.apache.org/incubator/TinkerPop> is seen as the JDBC <http://en.wikipedia.org/wiki/Java_Database_Connectivity> of the graph computing community. B. Proposal TinkerPop <https://wiki.apache.org/incubator/TinkerPop> was formed in 2009 and is currently in the milestone series of 3.0.0. From the start, TinkerPop <https://wiki.apache.org/incubator/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 <https://wiki.apache.org/incubator/TinkerPop3>, the license was changed to Apache2. The TinkerPop <https://wiki.apache.org/incubator/TinkerPop> team is composed of developers, evangelists, and representatives from graph system vendors (see TinkerPop Contributors <http://www.tinkerpop.com/docs/3.0.0-SNAPSHOT/#tinkerpop-contributors> for more information). TinkerPop <https://wiki.apache.org/incubator/TinkerPop> has done its best to remain vendor agnostic and works closely with all vendors to ensure that the constructs within TinkerPop <https://wiki.apache.org/incubator/TinkerPop> are able to accommodate the requirements of the underlying graph system. To date, 12 "TinkerPop <https://wiki.apache.org/incubator/TinkerPop> recognized" graph system vendors provide TinkerPop <https://wiki.apache.org/incubator/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 TinkerPop <https://wiki.apache.org/incubator/TinkerPop> has had steady, active development since 2009 when it was founded. Over the years, the Gremlin query language within TinkerPop <https://wiki.apache.org/incubator/TinkerPop> has been adopted by various JVM languages and as such, there exists Gremlin-Groovy, Gremlin-Scala, Gremlin-Clojure, Gremlin-JavaScript <https://wiki.apache.org/incubator/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 <https://wiki.apache.org/incubator/TinkerPop> is not bound to the JVM in that developers wishing to interact with a TinkerPop <https://wiki.apache.org/incubator/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 <https://wiki.apache.org/incubator/TinkerPop> is being used is production graph-based applications around the world and is only getting better with age. D. Rationale The graph computing space has grown over the years to encompass numerous graph database and graph processing systems. TinkerPop <https://wiki.apache.org/incubator/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 <https://wiki.apache.org/incubator/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 The goal of this proposal is to migrate TinkerPop <https://wiki.apache.org/incubator/TinkerPop> to The Apache Software Foundation to 1. get more exposure to the project 2. legally protect the developers and contributors of the project 3. ensure that TinkerPop <https://wiki.apache.org/incubator/TinkerPop> has a vendor-neutral, stable home for the future F. Current Status TinkerPop <https://wiki.apache.org/incubator/TinkerPop> is planning to release TinkerPop <https://wiki.apache.org/incubator/TinkerPop> 3.0.0.GA early 2015. We would like to release TinkerPop <https://wiki.apache.org/incubator/TinkerPop> 3.0.0.GA at the Apache Software Foundation. G. Meritocracy TinkerPop <https://wiki.apache.org/incubator/TinkerPop> already has an established community that values meritocracy. Anyone is welcome to contribute to TinkerPop <https://wiki.apache.org/incubator/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 <https://wiki.apache.org/incubator/TinkerPop> as committers. Moreover, TinkerPop <https://wiki.apache.org/incubator/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. H. Community The TinkerPop mailing list <https://groups.google.com/forum/#!forum/gremlin-users> 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 <https://wiki.apache.org/incubator/TinkerPop> ecosystem by providing language bindings and system implementations. While not contributing to the core codebase per se, they supportTinkerPop <https://wiki.apache.org/incubator/TinkerPop> via their software and lecture outreach. I. Core developers The initial committer list is small, and we hope to grow that into a larger, vibrant community at the Apache Software Foundation. J. Alignment TinkerPop <https://wiki.apache.org/incubator/TinkerPop> is licensed Apache2. The OLAP reference implementation that distributes with TinkerPop <https://wiki.apache.org/incubator/TinkerPop> is based on Hadoop <http://hadoop.apache.org/> and Giraph <http://giraph.apache.org/>. There has been a push from vendors and commercial organizations interested in ensuring TinkerPop <https://wiki.apache.org/incubator/TinkerPop> has the legal support of a software foundation. We believe The Apache Software Foundation to be a great home for TinkerPop <https://wiki.apache.org/incubator/TinkerPop>. K. Known Risks & Abandoned projects TinkerPop <https://wiki.apache.org/incubator/TinkerPop> is currently at TinkerPop <https://wiki.apache.org/incubator/TinkerPop> 3.0.0.M6. There is a significant amount of code developed since TinkerPop <https://wiki.apache.org/incubator/TinkerPop>'s inception. We have done our best to secure CLAs from contributors. To date did not have any legal or political issues. TinkerPop <https://wiki.apache.org/incubator/TinkerPop> has 12 official graph vendors that maintain or support a TinkerPop <https://wiki.apache.org/incubator/TinkerPop> implementation for their system. If, lets say, 75% of those vendors decide against providing a TinkerPop <https://wiki.apache.org/incubator/TinkerPop> interface, then this would be detrimental to TinkerPop <https://wiki.apache.org/incubator/TinkerPop>'s efforts. With that, it is very important that TinkerPop <https://wiki.apache.org/incubator/TinkerPop> remain neutral and engaged with vendors. L. Inexperience with Open Source The primary developers of TinkerPop <https://wiki.apache.org/incubator/TinkerPop> have been producing TinkerPop <https://wiki.apache.org/incubator/TinkerPop> open source code and releases in full public view since 2009 via both our GitHub <https://wiki.apache.org/incubator/GitHub> repository and our public mailing lists. We pride ourselves in professional software, documentation, and aesthetics. With its integration to numerous graph systems in the market, we see TinkerPop <https://wiki.apache.org/incubator/TinkerPop> as a masterpiece in the open source space. We are working with both open source and commercial entities to ensure a solid, respected product. M. Homogeneous Developers The initial set of committers all hail from different employers. N. Reliance on Salaried Developers TinkerPop <https://wiki.apache.org/incubator/TinkerPop> is open source and no individual is paid for their contributions except for our logo designer. All the logos and documentation graphics are released Apache2. O. Relationships with Other Apache Projects TinkerPop <https://wiki.apache.org/incubator/TinkerPop> currently leverages Hadoop, Giraph, and in the near future, will integrate with Spark <https://spark.apache.org/>. Internally, the project leverages Maven3, Apache Configuration, and Apache Commons. P. An Excessive Fascination with the Apache Brand TinkerPop <https://wiki.apache.org/incubator/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 <https://wiki.apache.org/incubator/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 <https://wiki.apache.org/incubator/TinkerPop>. With that said, TinkerPop <https://wiki.apache.org/incubator/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 TinkerPop book <http://www.tinkerpopbook.com/> 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. Q. Documentation TinkerPop <https://wiki.apache.org/incubator/TinkerPop> takes pride in its documentation: AsciiDoc <https://wiki.apache.org/incubator/AsciiDoc> http://www.tinkerpop.com/docs/3.0.0-SNAPSHOT/ JavaDoc <https://wiki.apache.org/incubator/JavaDoc> (core) http://www.tinkerpop.com/javadocs/3.0.0-SNAPSHOT/core/ JavaDoc <https://wiki.apache.org/incubator/JavaDoc> (full) http://www.tinkerpop.com/javadocs/3.0.0-SNAPSHOT/full/ R. Initial Source TinkerPop <https://wiki.apache.org/incubator/TinkerPop> is currently hosted on GitHub <https://wiki.apache.org/incubator/GitHub>: https://github.com/tinkerpop/. The following repositories would like to be migrated to ASF.
