= RCF, a rich component library for JSF =

=== Abstract ===

RCF is a rich (Ajax-style) component set for the JavaServer Faces(tm) 1.2 technology. .

=== Proposal ===

RCF is an Ajax-based component library for the JavaServer Faces technology. RCF comes with
very high quality components, and skinning (CSS-based) capabilities. RCF features include:
file upload support, client-side conversion and validation, a complete Ajax-integration, data
tables, hierarchical tables, color/date pickers, menu tabs/buttons, wizards, popups, toolbars,
toolboxes, internationalization and accessibility. This project starts with more than 100
components which have already been documented and thoroughly tested. 

RCF stands for Rich Client Framework and it means that web applications, using this component
set look very similar to a real, native desktop application. The name for this project can
be a subject to change.

RCF depends on some artifacts, provided by the Apache Trinidad project, such as framework
features or Apache Maven plug-ins.

=== Background ===

The development of RCF started in 2005 at Oracle Corporation. With the advent of Ajax and
the higher requirements for a very rich user experience, Oracle decided to implement a rich/Ajax-style
JSF component set. The goal was to advance the already existing ADF Faces product, donated
to the ASF in early 2006 (Apache Trinidad). When the development of RCF started, there wasn't
any JSF component set that provides similar richness to the user. The RCF components run on
any JSF 1.2 compliant implementation. RCF is based on some internal features of the Apache
Trinidad project.

The JavaServer Faces technology is a very important technology for the RCF component set,
since RCF requires JSF as its runtime environment. Oracle has a large commitment to both open
source and open standards. This proposal illustrates Oracle’s commitment to the success
of the JSF standard and supporting the open source community by providing a rich component
set under a liberal license, the Apache 2.0 license.

=== Rationale ===

The project is interested in moving to Apache for the following reasons: To provide Apache-licensed
implementation of a full-blown Ajax-based JSF component set, to become better integrated with
the MyFaces and Shale initiatives, and to build a strong vendor-neutral community that will
outlast any one person’s or company’s participation.

=== Initial Goals ===

The initial goals of the proposed project are:

 * Viable community around the RCF code base
 * Active relationships and possible cooperation with related projects and communities, such
as Apache MyFaces (and it’s subprojects) or Apache Trinidad.

== Current Status ==

=== Meritocracy ===

All the initial committers are familiar with the meritocracy principles of Apache, and have
already worked on the various source code bases. Some of the initial committers also have
experience, undergoing the Apache incubation process. We will follow the normal meritocracy
rules also with other potential contributors.

=== Community ===

The Apache MyFaces project, the Apache Trinidad podling and the JavaServer Faces standard
hold great promise. A fully Ajax-based set of user interface components will significantly
accelerate their adoption. We strongly believe that RCF will gather significant momentum and
enough developers to build a vibrant community of users and contributors.

=== Core Developers ===

Four of the initial committers are Oracle employees and all are committers on the Apache Trinidad
podling. One of them is a committer at Apache MyFaces and Apache Shale. Four of the initial
committers are committers on the Apache MyFaces project. RCF was developed by Oracle employees.

=== Alignment ===

RCF aligns perfectly with Apache MyFaces, Apache Trinidad and other ASF projects utilizing
J2EE infrastructure such as Tomcat or Shale. Of particular relevance are projects such as
Geronimo, Apache libraries like Jakarta Taglibs and Apache Maven.

== Known Risks ==

=== Orphaned products ===

Most of the active developers would like to become RCF Committers or PMC Members and have
long term interest to develop and maintain the code.

=== Inexperience with Open Source ===

All the initial developers have worked on open source before and many are committers and PMC
members within other Apache projects.

=== Homogenous Developers ===

Four of the initial committers are Oracle employees. The developers are experienced and very
familiar with distributed, multi-national, asynchronous environments. Also Oracle will most
likely influence developers across the globe to join the RCF community.

=== Reliance on Salaried Developers ===

Some of the initial committers are salaried developers employed by Oracle. Oracle is committed
to standards and open source and committed to building a vibrant and diverse community around
this project. The remaining developers are individual volunteers who are passionate about
the technology. The donating company has reached out and will continue to reach out in its
effort to build a diverse community.

=== Relationships with Other Apache Products ===

RCF will likely be used by a Java EE 5 (web) compliant container, like Geronimo or Tomcat
6, requires some Apache products (Shale Test, commons digester, commons beanutils, Trinidad,
Xerces), and will support Apache MyFaces.

=== An Excessive Fascination with the Apache Brand ===

All of us are familiar with Apache and we have participated in Apache projects as contributors,
committers, and PMC members. While we expect the Apache brand may help attract more contributors,
our interests in starting this project is based on the factors mentioned in the Rationale
section. However, we will be sensitive to inadvertent abuse of the Apache brand and will work
with the Incubator PMC and the PRC to ensure the brand policies are respected.

== Documentation ==

There isn’t a documentation at the moment, but Oracle is actively working on developing
comprehensive documentation for RCF and that documentation will be provided soon or upon availability.

== Initial Source ==

The initial code base is owned by Oracle. The applicable code will be re-licensed under the
Apache License 2.0. All dependencies have Apache compatible licenses. These include BSD and
CDDL licensed dependencies.

== External Dependencies ==

All dependencies have Apache compatible licenses. These include BSD and CDDL licensed dependencies.
