Amber has been incubating since July 2010. Amber is a project to develop a Java library which provides an API specification for, and an unconditionally compliant implementation of the OAuth v1.0, v1.0a and v2.0 specifications. OAuth is a mechanism that allows users to authenticate and authorise access by another party to resources they control while avoiding the need to share their username and password credentials.

The most important issues that must be addressed before graduation are:

 - Attract users and developers
 - Generate a release

The Incubator PMC / ASF Board should be aware that:

 - Community activity is relatively low

How has the community developed since the last report

 - Some users have started asking for help or getting started guides on the mailing list

How has the project developed since the last report

Jena was accepted into the Apache Incubator November 2010. It is an existing project migrating to ASF. It has a large codebase that provides a semantic web framework in Java that implements
the key W3C recommendations for the core semantic web technologies of

Three most important issues to address for graduation:

* Create a code base in Apache with legal clearance.
* Establish the Apache-based community for developers, contributors and
* Create and communicate open project processes aligned to Apache

Issues for the Incubator PMC or ASF Board:


Community development:

We have started to advertise the existence of Apache-hosted mailing lists. Traffic on these lists continues to grow.

A new work area on enhancing the native storage system with transaction support is being conducted in public on Apache cwiki and mailing lists.

Project development:

We have received the software grant from HP; HP has copyright on the majority of the codebase.  We can now migrate the code to Apache infrastructure, and contact previous contributors for the remaining areas (these are small in number and scope).

Libcloud is a unified interface into various cloud service providers,
written in Python. Libcloud joined the Incubator on 3 November 2009.

During this month we have addressed all of the open graduation issues and started a TLP voting thread on the incubator mailing list.


The Libcloud community continues to grow at a nice steady pace. In the past few months we have received multiple community contributions, some of them are listed bellow:

- compute driver for
- compute driver for
- compute driver for the OpSource cloud
- compute driver for OpenStack (not merged yet, still working with the original author on polishing it and resolving some open issues)
- libvirt proof-of-concept compute driver (not merged yet, still debating on how we can fit it into our project)

During this month (May) we have also agreed upon a new chair (Tomaz Muraus).

To make our website more easy to update and more relevant to the users we have ported it to the Apache CMS and added two new sections - "Community resources" and "Contributing". 

Some of the Libcloud developers have also been present at PyCon in Atlanta in March where we have held a sprint.

As part of our ongoing effort to engage the community and inspire new contributors, one of the committers will give a talk about Libcloud at EuroPython 2011 in Italy where we will also held a sprint.


The last stable release of Libcloud is 0.4.2 which was released on January 17th. We are currently working towards 0.5.0 which is considered as a big milestone, because it will include many new features, fixes and improvements:

- new Storage API
- new Load-balancer API
- new compute drivers
- fixes in the existing compute drivers
- increased test coverage

This version is planned to be released before the end of May.

Lucene.Net was accepted into the Apache Incubator in February 2011. Originally it was a sub project of the Lucene Project.

Lucene.Net is a port of the Lucene search engine library, written in C# and targeted at .NET runtime users. Lucene.Net has three primary goals: 
* Maintain the existing line-by-line port from Java to C#, fully automating and commoditizing the process such that the project can easily synchronize with the Java Lucene release schedule.
* High-performance C# search engine library.
* Maximize usability and power when used within the .NET runtime. To that end, it will present a highly idiomatic, carefully tailored API that takes advantage of many of the special features of the .NET runtime.

Recent Activity:

* Lucene.Net 2.9.4 is in the trunk and currently being tested
* Continuous Integration, Unit Testing, and Code Coverage has been fully vetted

Current Activities:

* Release Lucene.Net 2.9.4
* Refactoring of project files for the main trunk, allowing us to fully implement CI, Unit Testing, and Code Coverage
* Develop a process to automatically (as much as possible) convert the Java Lucene code to C# (to maintain our line by line port)

Goals for graduation:

* Have a nearly fully automated process to convert Java Lucene to C#.
* Release Lucene.Net 3.0.3 (port of Java Lucene 3.0.3)
* Have a new .NET version of Lucene utilizing .NET constructs and idioms

NPanday allows projects using the .NET framework to be built with Apache Maven. NPanday allows .NET projects to be converted into Maven projects thus allowing them to fully utilize the other technologies driven by Maven. NPanday has been incubating since August 2010.

In our previous report (February 2011), we stated that we've staged the NPanday-1.3-incubating release. However, there were a couple of issues that we needed to address so we decided to not push through with it. 

After addressing those issues, we've staged the NPanday-1.4.0-incubating release for vote which includes the following issues:

    * Visual Studio 2010 and .Net 4.0 Framework support
    * Removal of UAC and PAB directories
    * Updated groupIds of all NPanday components including plugins to "org.apache.npanday"

This release is still waiting for other committers and mentors to test and get the required binding votes.

Updated documentation was successfully deployed in

Code licenses and license headers have all been reviewed and pass RAT.

IP clearance was completed.

We have voted a new committer in the person of John Fallows and we also have a new mentor, Matthias Wessendorf.

The top priorities towards graduation are:

* complete 1.4.0-incubating release

* guide regular patch contributors towards becoming committers

* improve engagement of existing committers

There are no issues for the Incubator PMC or board at this time.

OpenNLP is a machine learning based toolkit for the processing of natural language text. It supports the most common NLP tasks, such as tokenization, sentence segmentation, part-of-speech tagging, named entity extraction, chunking, parsing, and coreference resolution. These tasks are usually required to build more advanced text processing services.

OpenNLP entered incubation on 11/23 2010.

We just did our first Apache release on 2nd of May and are now planning which features/work will go into the next release. For instance we started to discuss/plan a big refactoring of our machine learning code, custom feature generation for the name finder, dictionary support for the name finder, etc. 

There is still good traffic on both the user and dev mailing list. A couple of users asked questions about how OpenNLP can be trained for new languages.

A list of the the most important issues to address in the move towards graduation:
 * Resolve potential IP issues around releasing training models
 * Establish open regression tests for the parser and coreference component

Apache SIS is a toolkit that spatial information system builders or users can use to build applications containing location context. This project will look to store reference implementations of spatial algorithms, utilities, services, etc. as well as serve as a sandbox to explore new ideas. Further, the goal is to have Apache SIS grow into a thriving Apache top-level community, where a host of SIS/GIS related software (OGC datastores, REST-ful interfaces, data standards, etc.) can grow from and thrive under the Apache umbrella.

* Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be aware of?

Not at this time

* Community progress since the last report

Since SIS released its first release 0.1-incubating in November 2010, development has slowed down. This is a small core set of committers and community though. We haven't had a lot of user mailing list activity. 

We should try and target a 0.2-incubating release with a layer service and some basic integration with Apache Tika (a GDAL parser is being worked on in that community with an eye towards integration into SIS). Also we are looking at Apache OODT as a mechanism for geospatial storage and persistence. 

There has been renewed interest from ESRI and we are pursuing this as well.

* Project progress since last report

SIS was voted into the Incubator by the IPMC on February 21, 2010.

Development progress since the 0.1-incubating release has been modest, focusing primarily on the community development mentioned above. There has been some internal effort at JPL to integrate SIS into ongoing projects such as the CO2 Portal, the CMDS project and others. We hope to begin the push towards 0.2-incubating as specified above.
