Subject RE: [PROPOSAL] Dimensions Proposal
Date Mon, 07 Jan 2008 13:40:05 GMT

FYI, Dimensions is already the name of a software developed by Serena.  See [1]

I know it's a criterion to leave and not to enter the incubator, but I prefer to share this
info before I forget.

> == Dimensions, a multi-channel framework Proposal ==
> 
> === Abstract ===
> 
> Dimensions is an Apache Tiles extension that delivers customized
> content for different users, devices or other criteria.
> 
> === Proposal ===
> 
> The Dimensions extension for Apache Tiles is capable of delivering
> different "aspects" of the same website. By recognizing the calling
> user and its devices, it organizes the pages using different layout,
> depending on the developers configuration.
> 
> This is especially useful for multi-channel websites, to allow a wider
> range of users to visit a site, by reducing the size of pages for
> smaller screens, or by showing certain page sections only if a user
> has sufficient credentials.
> 
> Dimensions natural place is as an Apache Tiles extension, since it
> relies on Tiles' concepts, like "definition" and "DefinitionsFactory",
> and it cannot exist without Tiles.
> 
> === Background ===
> 
> The initial idea was (here goes initial story by Aaron Roller).
> 
> But in 2004 the ability of delivering different contents was extended
> not only on different calling devices, but also on different calling
> users role. This kind of capability is enabled by using configuration
> files, that maps all user roles/device crosspoints to a certain site
> layout.
> 
> The concept of a "dimension" arised: the user role was a dimension,
> while the device was the other. But this kind of concept can be
> extended infinitely, allowing to create a n-dimensional space in which
> each crosspoint is a website layout.
> 
> === Rationale ===
> 
> Currently, when a Java EE website needs to be ported for other
> devices, it needed the creation of a new project, or at least a new
> section of the same project. This kind of procedure can lead to code
> repetition and lack of coherence.
> 
> Dimensions solves this problem by providing customized aspects for the
> same website: only the visible part of it will change (depending on
> the condition imposed by the developer), but the rest of it will
> remain the same, including the "controller" and "model" part of the
> application.
> 
> === Initial Goals ===
> 
> The initial goals of the proposed project are:
>   * Include the Apache Software Foundation header in all source code.
>   * Viable community around the Dimensions codebase.
>   * Active relationships and possible cooperation with related
> projects and communities, especially those that include Apache Tiles
> support.
>   * Clean-up of the code, by following the Apache Tiles standard.

> ==== Current Status ====
> 
> ===== Meritocracy =====
> 
> All but one (here I suppose that Aaron will be a committer) initial
> committers are familiar with the meritocracy principles of Apache, and
> have already worked on the various source codebases. The missing one
> contributed to several open source projects and probably will learn
> very fast. We will follow the normal meritocracy rules also with other
> potential contributors.
> 
> ===== Community =====
> 
> Dimensions community will be, probably, Apache Tiles community. But
> there are a number of similar targeted projects around the WWW that
> could help in creating a broader one.
> 
> ===== Core Developers =====
> 
> The initial set of developers comes from various backgrounds, as they
> are in Apache Tiles project, with different but compatible needs for
> the proposed project.
> 
> ===== Alignment =====
> 
> Dimensions will likely be widely used by various open source and
> commercial projects that have a dependency on Apache Tiles.
> 
> ==== Known Risks ====
> 
> ===== Orphaned products =====
> 
> There is a risk of making Dimensions an orphaned product, but most
> probably it will follow Apache Tiles steps. Since Tiles is widely
> adopted in Java EE applications, it is difficult that Dimensions will
> be abandoned.
> 
> ===== Inexperience with open source =====
> 
> All the initial developers have worked on open source and all but one
> are PMC members of Apache Tiles.
> 
> ===== Homogeneous developers =====
> 
> The initial developers come from a variety of backgrounds and with a
> variety of needs for the proposed extension.
> 
> ===== Reliance on salaried developers =====
> 
> Dimensions does not rely on salaried developers.
> 
> ===== Relationships with Other Apache Products =====
> 
> Dimensions is strongly related to Apache Tiles to the point that it
> should be a subproject of it.
> 
> Dimensions relies on Tiles' concepts, like "definition" and
> "DefinitionsFactory". Dimensions cannot exist without Tiles.
> 
> ===== An Excessive Fascination with the Apache Brand =====
> 
> All but one of us are familiar with Apache and we have participated in
> Apache projects as contributors, committers, and PMC members. The one
> that did not, will follow our example easily. We feel that Apache
> Tiles is a natural home for a project like this.

> === Documentation ===
> 
> The official documentation is hosted in a Sourceforge website:
> [http://mutidimensions.sourceforge.net/]
> 
> The [http://www.w3.org/Mobile/CCPP/Historic-CCPP1 CC/PP standard] is
> used to recognize certain devices..
> 
> === Initial Source ===
> 
> Dimensions will take all of his source code from
> [http://mutidimensions.sourceforge.net/ its Sourceforge site].
> 
> === Source and Intellectual Property Submission Plan ===
> 
> All source code is copyrighted by Aaron Roller, Free2Be LLC, Antonio Petrelli.
> (I think that there is a problem with Free2Be LLC, probably it changed
> name, that should be addressed).
> 
> === External Dependencies ===
> 
> Dimensions depends on Apache Tiles and some Jakarta Commons libraries.
> The only dependency outside of Apache is [http://www.dom4j.org/
> DOM4J], that is BSD-style licensed.
> 
> === Cryptography ===
> 
> Dimensions does not handle cryptography in any way.
> 
> === Required Resources ===

> ==== mailing list(s) ====
> 
> During incubation, the Dimensions team could make use of the usual set of lists
>   * dimensions-user AT incubator DOT apache DOT org
>   * dimensions-dev AT incubator DOT apache DOT org
>   * dimensions-commits AT incubator DOT apache DOT org
> 
> until Dimensions really joins Apache Tiles.

>  * Dimensions (DIMS) inside [https://issues.apache.org/struts/ Struts
