[DISCUSS] Olympian Incubation Proposal
Hi All,
Please find below a proposal for a new incubator podling, Apache Olympian,
formerly Titan.
Apache Olympian is software designed to support the processing of graphs so
large that they require storage and computational capacities beyond what a
single machine can provide.
This project will be a fork of Titan graph database project (
https://github.com/thinkaurelius/titan/) that already come with Apache
License v2.0.
The project was created by company called Aurelius and was acquired by
Datstax.
Coming to 2016 there has been less activity in the project as the original
authors are busy with other software development, but there is significant
interest from the community (see https://groups.google.com/forum/#!msg/
aureliusgraphs/jEN_7QwVXZ4/mz3gik-FAgAJ)
The community have tried to reaching out to Datastax to donate the
copyright and trademark of project to ASF but it was not approved.
Because of that, the community has decided to go to ASF with different
name: Apache Olympian.
The wiki proposal page is located at this URL:
https://wiki.apache.org/incubator/OlympianProposal
I have also included the current text of that page below.
Looking forward of comments or questions about this proposal.
Thanks,
Henry Saputra
On behalf of Apache Olympian community
= Apache Olympian Proposal ==
== Abstract ==
Olympian (formerly Titan) is software designed to support the processing of
graphs so large that they require storage and computational capacities
beyond what a single machine can provide. Scaling graph data processing for
real time traversals and analytical queries is Olympian’s main benefit.
== Proposal ==
Olympian consists of about 75K of Java code under the Apache 2 license
<http://www.apache.org/licenses/LICENSE-2.0>. It supports very large
graphs, with many concurrent transactions and operational graph processing.
Olympian graphs scale with the number of machines in the cluster. Olympian
already integrates with a number of Apache projects:
-
Provides native support for the popular property graph data model
exposed by Apache TinkerPop <http://tinkerpop.apache.org/>.
-
Provides native support for the Gremlin graph traversal language defined
by Apache TinkerPop for programming language agnostic connectivity.
-
Provides graph persistence solutions with:
-
Apache Cassandra <http://cassandra.apache.org/>
-
Apache HBase <https://hbase.apache.org/>
-
Provides advanced indexing with:
-
Apache Lucene <https://lucene.apache.org/>
-
Apache Solr <http://lucene.apache.org/solr/>
-
Supports global graph analytics and batch graph processing through
the Apache
Hadoop <http://hadoop.apache.org/> framework with processors implemented
with:
-
Apache Spark <http://spark.apache.org/>
-
Apache Giraph <http://giraph.apache.org/>
Other software Olympian interfaces with includes:
-
BerkeleyDB
-
Elasticsearch
== Background ==
Marko Rodriguez and Matthias Broecheler, cofounders of the Aurelius graph
consulting firm, developed the Titan distributed graph database system and
made it available under the Apache 2 license in 2012. Marko is also a
cofounder of the Apache TinkerPop project and the primary developer of the
Gremlin graph traversal language. Other developers of Titan include Dan
LaRocque, Stephen Mallette, Daniel Kuppitz, and Pavel Yaskevich. Datastax
acquired Aurelius in February 2015, prior to the Titan 1.0 release in
September 2015.
Since Titan became available on GitHub, there have been 4434 commits, 38
branches, 23 releases, and 35 contributors. In 2016 there has been less
activity as the original authors are busy with other software development,
but there is significant interest from the community.
== Rationale ==
(1) There are a number of Apache projects that integrate with Titan.
(2) Apache Atlas (incubating) <http://atlas.incubator.apache.org/> packages
and ships Titan as an essential component, yet Titan is not part of Apache.
(3) There are a number of existing users of Titan who are keen to continue
to develop the code. These users provide the basis of the community for the
proposed project.
== Initial Goals ==
The initial goals are as follows:
-
Establish the project governance in The Apache Way and broaden the
community.
-
Distribute an incubating release aligned with the latest Apache
TinkerPop version and prepared in accordance with the Apache release
process.
-
Improve the documentation.
-
Add more unit/scenario tests.
-
Contribute functional and performance-related enhancements to the code.
== Current Status ==
The project will be forked off the existing Titan code base. This code has
been available under the Apache 2 License but has not been subject to the
Apache governance. The proposed project will adhere to Apache’s governance
and processes. This is one of the key benefits and reasons for bringing the
project forward as an incubator candidate.
There are 37 pull requests currently open against Titan, and the last pull
request was merged in June 2016. During incubation, the community will
adopt a voting-based approach to review and commit those changes into the
code base in preparation for the first incubating release.
=== Meritocracy ===
The proposed project will adopt the familiar process of progression from
submitter to contributor to PMC. The community includes active committers
and PMC members on other Apache projects (e.g. Apache TinkerPop, Apache
Atlas (incubating), Apache HBase).
=== Community ===
There is an active and passionate community of existing Titan users. It is
believed that this community will continue to grow and to progress. Titan
is well-designed to support different backends, and the community will
naturally grow as more backends are written to fit into the Titan
architecture. Since the Titan 1.0 release, 3 different storage providers
have become available. Also once an incubation release is made available,
the community will likely see quick adoption from the Apache TinkerPop user
base.
=== Core Developers ===
The community includes developers from a number of vendors (e.g. Google,
HortonWorks, IBM, Mindmaps, Classmethod) and users (both academic and
commercial). It contains two active committers and PMC members from the
Apache TinkerPop project, one active committer and PPMC member from Apache
Atlas (incubating), and one committer from Apache HBase. The developers
represent a good mixture of skills, including expertise with each of the
supported providers.
=== Alignment ===
The proposed project will be used by or integrated with a number of other
Apache components, including (probably) TinkerPop, Atlas, Hadoop, Spark,
Cassandra, and HBase. It is logical that the project should also be homed
within Apache and subject to the governance principles of Apache.
== Known Risks ==
=== Orphaned products ===
All the companies and developers associated with academic institutions who
are engaged or want to be engaged with Titan are well aware of the open
source philosophy and the importance of open governance of open source
products. Hence, we think the risks of Titan being orphaned are minimal.
=== Inexperience with Open Source ===
The project is based on an existing open source code base (Titan 1.0) and
the community consists of developers and vendors who have a history and
strategy of open development and governance. The initial committers include
committers and PMC members from other Apache projects.
=== Homogenous Developers ===
The community consists of geographically-dispersed volunteers from academic
and a range of commercial organisations. The geographic diversity includes
North America, Europe, Asia, and Australia.
=== Reliance on Salaried Developers ===
Many of the developers are salaried by the vendors in the community, but
the vendors have publicly stated their support for open systems and whilst
we might expect to see some gradual replacement of members of the
community, we believe that it will remain stable and viable into the
future. All members of the community are passionate about the project and
are likely to contribute outside of ‘normal working hours’.
=== Relationships with Other Apache Products ===
The proposed project has dependencies on other Apache projects, including
Cassandra and HBase, for example. There are Apache projects that depend
upon the availability of an open, scalable graph database. Apache Atlas is
an example of such a project. Apache S2Graph (incubating)
<https://s2graph.incubator.apache.org/> is currently an incubator project
at Apache, however it does not currently implement the Apache TinkerPop
interfaces, although it has an open JIRA for that effort.
=== An Excessive Fascination with the Apache Brand ===
Whilst the Apache brand will help to attract developers and consumers to
the project, it is not for this reason that the proposal is being made. It
is to align the governance of the project with that of the other components
with which it is commonly used and to benefit from the development
principles adopted by Apache. In particular, TinkerPop is Titan’s most
critical component/dependency, one so tight that Titan releases are
contemporaneous or follow TinkerPop releases.
== Documentation ==
Information on the existing Titan code base can be found at:
http://titan.thinkaurelius.com/
== Initial Source ==
The initial source will be based off a fork of the Titan code base. The
latter can be found at: https://github.com/thinkaurelius/titan. The fork to
be used as the base is from: https://github.com/pluradj/titan
== Source and Intellectual Property Submission Plan ==
Since Datastax owns the copyright and trademark for Titan, when the
proposal is accepted to the ASF Incubator, the community will choose a
different name. It is proposed that Titan will enter incubation with the
name Olympian. The community will finalize and document the name research
during incubation. Individuals in the community have discussed the
possibility of a software grant from Datastax, but Datastax was not
interested in donating code or brand to the ASF. When asked if they would
block others taking it to Apache they did not respond.
== External Dependencies ==
Titan has the following external dependencies:
* Java 1.8
* Apache Maven 3.0.5 (Apache 2.0 License)
* JUnit 4.12 (EPL)
* MRUnit 1.1.0 (Apache 2.0 License)
* Apache Cassandra (Apache 2.0 License)
* Jamm (Apache 2.0 License)
* Metrics 2.1.1 and 3.0.1 (Apache 2.0 License)
* Sesame 2.7.10 (Eclipse Public License Version 1.0)
* slf4j 1.7.5 (MIT)
* Apache HTTPComponents 4.4.1 (Apache 2.0 License)
* Apache Hadoop 1.2.1 & 2.7.1 (Apache 2.0 License)
* Apache HBase (Apache 2.0 License)
* Jackson 1.9.2 & 2.4.4 (Apache 2.0 License)
* Apache Lucene 4.10.4 (Apache 2.0 License)
* Elasticsearch 1.5.1 (Apache 2.0 License)
* Apache Commons Beanutils 1.7.0 (Apache 2.0 License)
* Joda Time 1.6.2 (Apache 2.0 License)
* Google ConcurrentLinkedHashMap (Apache 2.0 License)
* Antlr 2.7.7 And 3.2 (BSD License)
* ASM 3 & 4 (http://asm.ow2.org/license.html)
* Apache Zookeeper 3.4.6 (Apache 2.0 License)
* Jersey 1.9 (CDDL 1.1 and GPL v2)
* JNA 4.0.0 (LGPL 2.1 and Apache 2.0 License)
* Kuali Maven s3 Wagon 1.1.20 (Educational Community License, Version 2.0)
* Apache Tomcat Jasper 5.5.23 (Apache 2.0 License)
* Berkeley DB 5.0.73 (Sleepycat License)
Upon acceptance to the incubator, we would begin a thorough analysis of all
transitive dependencies to verify this information and introduce license
checking into the build and release process by integrating with Apache
Rat. In the case where a dependency has an Apache incompatible license,
such as Berkeley DB, we will remove or replace it with an appropriate
alternative.
== Cryptography ==
Titan will support encryption of client-server communication through its
use of the Apache TinkerPop Gremlin Server. We do not expect Titan to be a
controlled export due to its use of encryption.
== Required resources ==
=== Mailing lists ===
* private@olympian.incubator.apache.org (with moderated subscriptions)
* commits@olympian.incubator.apache.org
* dev@olympian.incubator.apache.org
* user@olympian.incubator.apache.org
=== Git Repository ===
The team would like to use git for source control. We request a writable
git repo https://git-wip-us.apache.org/repos/asf/incubator-olympian.git,
and mirroring to be set up to GitHub through INFRA. We also request
configuration for continuous integration with Travis CI.
=== Issue Tracking ===
Titan currently uses the GitHub issue tracker and the team would like to
migrate all of these issues to the Apache JIRA.

I think we are in similar situation like Metron (https://wiki.apache.org/
incubator/MetronProposal) where there is also need to fork from original
repo.

> > > >> The community consists of geographically-dispersed volunteers

> > > >> geographic diversity includes North America, Europe, Asia, and Australia.
> > > >>
> > > >> === Reliance on Salaried Developers ===
> > > >>
> > > >> Many of the developers are salaried by the vendors in the

Re: [DISCUSS] Olympian Incubation Proposal
Posted by Ted Wilmes <tw...@gmail.com>.
Hello Ross,
Per another one of the proposal submitters, Misha Brukman: "Datastax is not
against the move of Titan to ASF but has stated that they will neither
support or block it, as long as it doesn't involve them participating or
signing the software grant" I've CC'ed him to get him onto this thread.

RE: [DISCUSS] Olympian Incubation Proposal
Posted by Ross Gardler <Ro...@microsoft.com>.
I see the GitHub code is untouched for over a year. Are Datastax objecting to the proposal or is it just that they are unwilling to actively supporting it?

Re: [DISCUSS] Olympian Incubation Proposal
Posted by Jean-Baptiste Onofré <jb...@nanthrax.net>.
Hi Susan,
community interest is the key part for sure. But we would like to avoid
any trouble about the grant agreement, etc.
Just my $0.01

JB

>> === Homogenous Developers ===
>>
>> The community consists of geographically-dispersed volunteers from academic

>> North America, Europe, Asia, and Australia.
>>
>> === Reliance on Salaried Developers ===

>>
>> === Relationships with Other Apache Products ===
>>
>> The proposed project has dependencies on other Apache projects, including

>>
>> === An Excessive Fascination with the Apache Brand ===
>>
>> Whilst the Apache brand will help to attract developers and consumers to
>> the project, it is not for this reason that the proposal is being made. It
>> is to align the governance of the project with that of the other components

Re: [DISCUSS] Olympian Incubation Proposal
Posted by Jason Plurad <pl...@gmail.com>.
The Titan community is serviced by the aureliusgraphs Google group, which
is actually moderated by Datastax employees. I started a thread last week
about continuing progress with Titan at Apache [1]. The intent with this
proposal is not to fracture the Titan community, rather to preserve it. The
community has been concerned about this for a long time with little
response from Datastax [2][3][4].
Development on Titan by Datastax appears to be abandoned. The latest
release of Titan was over a year ago. There is a titan11 branch with more
recent development, but the last commit on that branch was 4 months ago.
There are many pull requests ready for review/merge, including one to
update Apache TinkerPop support, but those appear to be waiting on efforts
from the lead Titan developers when they are free to do so [5]. The two
lead developers of Titan have not appeared on the Google group in over 6
months. The last message from Matthias: September 2015, Dan: March 2016.
We are aware of potential issues with the name Olympian. If accepted into
the incubator, further research and consideration on selecting a new name
will be done, as described in the proposal.

Re: [DISCUSS] Olympian Incubation Proposal
Posted by Susan Malaika <ma...@us.ibm.com>.
Hi JB
Datastax know about the incubator effort. As far as I know they will not sign the grant agreement. I was under the impression that the incubator proposal can proceed after discussion if there is sufficient community interest.

Hi Henry,
Is DataStax know and agree with the fork ?
Else, the Software Grant Agreement won't be possible and it won't be
able to easy to head to graduation.

Re: [DISCUSS] Olympian Incubation Proposal
Posted by Jean-Baptiste Onofré <jb...@nanthrax.net>.
Hi Henry,
Is DataStax know and agree with the fork ?
Else, the Software Grant Agreement won't be possible and it won't be
able to easy to head to graduation.

Re: Can you un-open-source a product? Re: [DISCUSS] Olympian
Incubation Proposal
Posted by Stian Soiland-Reyes <st...@apache.org>.
I think Apache should not take an active part in any forks, as it could
ruin the long-standing approval with the commercial community.
However I think going the Jenkins fork route is the way for these
communities that want to move forward:
Move to GitHub, change the name & logo, clean up IP, actively grow the
community (e.g. add to the GH organisation after 2 pull requests), make
frequent releases (not too ambitious design changes), have nice and
professional looking web pages, etc.
A bit of noise in the process is necessary so the fork gets attention. It
is a hostile fork, but community-backed. Give it a year or two, and the
fork could be stronger and independent - at which point I think ASF would
have less qualms about accepting the new community - it would kind of be
pre-incubated.
A GitHub fork also makes the fall shorter if the original copyright holders
change their mind and embrace Open Development; they can then (at least in
theory) re-merge the communities by approving the new name as "official
successor" and join the effort; perhaps at that point a move to ASF would
be a very good option to form new neutral ground.
Can you un-open-source a product? Re: [DISCUSS] Olympian Incubation Proposal
Posted by Greg Trasuk <tr...@stratuscom.com>.
I’m kind of curious how we’d apply our “Community over Code” credo to a situation like this.
It sounds like DataStax acquired a “community” centred on a product that had been open-sourced by its previous steward. And now their legal department is re-asserting control over the product. Fair enough, but if there’s a community that wants to carry on development against a product that was properly and fairly ASL2 licensed, does the acquirer have the right to shut them down? They certainly could assert control over the trademark that they own, but what if the community called it something else and carried on (which we generally require of an incubator product anyway)?
I’m obviously thinking of Hudson and Jenkins here - the community forked the code over a weekend, and Oracle was left with a dead product. When they asserted ownership of the “Hudson” trademark, the community simply said “OK, it’s Jenkins now”, and carried on.
If they had come to Apache, would we have shown them the door, for legalistic reasons? ( I don’t recall them coming to Apache at the time, but I could be wrong). Is it a “hostile fork” if the bulk of the community is in favour, and it’s only the trademark owner that demurs?
It seems to me that one of the goals of Apache is to have a “neutral” corporate entity to host open-source projects under open but orderly governance, so that an open-source project stands a chance of outlasting the mercurial whims of a commercial entity (and also of individual maintainers).
So I wonder if we’re being a little quick to shut down a community that wants open governance.
Cheers,
Greg Trasuk

Yes, with a few binding -1's there is nothing to discuss unless Datastax wish to reconsider. I doubt they want to discuss that on a public list.

Now that a move to the ASF is (currently) off the table, the community is regrouping to host the project elsewhere. Once basic infrastructure is in place there will likely be some sort of announcement. Proof will come.

That was my initial reaction as well, but then I thought some more and
ultimately
decided that expecting a bit more up-front community action was a
prudent choice.
What I'd like to see is a proof that ASF or no ASF the community wants to take
matters into its own hands and fork away. For now it isn't actually
obvious to me.

Agree with you on all points, Taylor.
And I am even quite surprised to see the number of people backing the
project, yet Apache is adamant to get involved. It feels a little bit like
the "Community over Code" and "Independent of any Corporate Influences"
have both received a big fat slap in their faces, and I think this hurts
the ASF more than any fallout with named corporation.
Disappointing to me...

Re: [DISCUSS] Olympian Incubation Proposal
Posted by "P. Taylor Goetz" <pt...@gmail.com>.
I think the community behind this proposal is ready to accept defeat at this point. With DataStax' objection, the project simply can't be brought under the auspices of the ASF unless DataStax reverses its stance.
Personally, I'm somewhat discouraged to see a company I once held in high regard in terms of supporting OSS and the ASF take this action. This represents a further erosion of that respect. It is what it is. I can't fault DataStax for trying to protect their bottom line. They are well within their rights here. It could be considered a stain on their relationship with the ASF, or not.
The community seems committed to moving forward with a fork, whether it is considered hostile or friendly. From discussions I've been privy to, if DataStax were to reverse their stance, this community would come back to the ASF in a heartbeat. There's a community behind this code, and they deserve the right to move forward.
I think they will, unfortunately not at the ASF. At least for now. Nothing would please me more than to see this community be able to come to Apache.

For the record I'd be -1 as well unless DataStax chose to support it.
I would like to give them time to change their mind though.

DataStax' reluctance to allow it could very easily be interpreted as a
rejection of the ASF governance model or the Foundation itself.
Yes, the community could certainly launch their fork at GitHub or some
such. DataStax provided them with that ability via the ALv2 license. The
ASF is not a necessary step for that community.

Yes, please read that thread, and my response.
Yes, DataStax’ current response would make this a hostile fork, but I think they should be given a chance to reconsider their stance.
The ASF doesn’t want to accept hostile forks. I understand and agree with that.
They can block a move to the ASF, but they can’t block a fork of the project moving elsewhere. Strong communities will regroup and live on. DataStax' reluctance to allow it could very easily be interpreted as a rejection of the ASF governance model or the Foundation itself.
DataStax has every right to block this. I also think it would behoove them not to for many reasons.
Can we wait and see if DataStax is willing to do the right thing before shooting down the proposal as a hostile fork?

+1 as a red flag, but not a blocker. For it to work, larger parts of the
existing contributors need to be convinced to join the Apache effort. There
are not license differences, so cross-pollination is possible.
Another concern is the name "Olympian", the International Olympic Committee
is well known for pursuing any use of their (real or perceived) trademarks.

I think the simplest definition of a "hostile fork" is this:
Does the copyright owner object to the fork?
Yes - it's hostile
No - it’s not hostile

Subject: Re: [DISCUSS] Olympian Incubation Proposal
In my mind a "hostile fork" is a fork of a project that goes against the wishes of the copyright holders and/or community.
I don't consider this proposal to be a hostile fork. In this case the community is eager to see the project move forward, but the owners of both the copyright and the keys to the castle (commit permissions) are no longer maintaining the project. Thus the community is left no other option than to fork in order to make any progress. The owners have also not expressed any resistance against the fork despite being asked several times. They have expressed an unwillingness to sign an SGA, but their silence when asked if they would move to block the proposal seems to indicate some level of approval (lazy consensus) to allow the proposal to move forward.
I would recommend, as was suggested earlier in this thread, that as champion Henry send a link to this discussion to legal@ and ask for guidance as to how to proceed.

Some clarification of what constitutes a “hostile fork” would indeed be useful. On a few occasions I have had discussions with communities on joining Apache, and this often comes up. We have relied on precedent — and in particular, on-the-record comments by board members on this list — and it has been working OK.
Bertrand, can you clarify what you mean by “author”. Do you mean copyright holder or you mean the individuals? (In this case it is moot, as DataStax is the copyright holder and the individuals are now mostly DataStax employees, but in other cases it is a material distinction.)

The precedent set by Bloodhound, and other projects suggest to me that
you could simply move forward after giving legal@ a heads up and just seeing
if there are any objections..or if lazy consensus just move forward and deal
with it during Incubation.

This sounds similar to the discussions we had about Bloodhound back in
early 2012 - Roy had some good comments about what we should or should
not accept, at https://s.apache.org/roy_forks_2012
It's not all black and white, but IMO we do need some form of
agreement from the original authors about the ASF taking control of
their code. Or maybe a demonstration that they really don't care about

Hi Bertrand,
I have a bit of a different understanding. We only accept code contributions
that want to be here. If the license for this project is ALv2 upstream from DataStax
then the community coming here for Olympian may fork the project and so long as
those committers and PMC part of the new project have ICLAs on file, there need not
be any informal agreement with any company. The company owns the name, the trademark,
etc., but the license allows forks and new communities to be made.
Cheers,
Chris

We only accept friendly forks, and it looks like Titan belongs to
DataStax, so IMO you need at least an informal agreement from them
before forking at the ASF.

When we asked DataStax if they would sign a code grant, they were clear that they would not. When we asked if they were opposed to us taking a fork to Apache, we got no response, despite trying on multiple channels. I don’t know if this is enough to accept the podling or not, but it’s the best we’re going to get.
