Subject Castafiore framework proposal to incubator
Date Tue, 03 Sep 2013 12:51:05 GMT
 Hello community,

please find below a proposal I wish to submit to the ASF. I am new here and
was told that I could paste the proposal here. So here we are.

Awaiting reply, recommendation and feedback and will be pleased to answer
any questions.

Thanks in advance

Kind regards,

Kureem Rossaye

Castafiore framework is a web frameworks, fully component oriented, ajax
based, one page appplication. Although the framework can be viewed as a
classical component oriented web framework like GWT, it has been designed
and implemented with a particular goal in mind. It is to be able to make
existing javascript libraries "java-able". Meaning that the framework
allows to easily take a javascript library like e.g jquery ui and use the
components and features via java. The integration of the javascript
libraries need to be easy and natural.

Actually companies like ext js and smartgwt have made their components
"java-able" using GWT. I wish to provide an alternative to gwt that is much
easier, fast, lightweight, and much more productive.

Castafiore framework has been designed and implemented with the following
goals in mind


   Fully object oriented

   Simple API that is very close to html itself
   We wanted an API that is closer to html markup and javascripts event
   model. I believe that this would help web developers easily visualize the
   rendering when reading source code.

   Write a full application with only java

   No need for compiler to convert to javascript like gwt.Javascript is
   rendered at runtime.

   The same API can be used to make an software that is server centric and
   or client centric. Meaning that the user can make part of his application
   server centric and part of his application client centric. He can of course
   choose to make the whole application client centric or server centric
   depending on the requirement. All of this using the same API.

   Low memory footprint

   Easy packaging of application. Everything can be packaged in a single
   jar. This includes images, css or javascript as well

   Same API used to create custom components. No need to external set of
   API or specific programming technique to create custom components. Creating
   a custom components should be done only the same way as writing an

   No need for javascript to create custom components.

   Although there is no need for javascript to create an application, it
   should be easy to integrate external javascript libraries and use them in
   java codes itself. This should be done is a natural way just like we would
   do in an HTML page. This should be like this so that javascript library
   authors with some java skills find it natural and easy to provide a
   castafiore component together with the library. e.g. The author of flexgrid
   should should find it easy to create a castafiore component thus making his
   library usable directly in java.

 *Actually, I wanted to create a java web framework for javascript
programmers. They should find it easy and fun to integrate and distribute
their js libraries as a castafiore component. They will be able to
distribute their libraries as a single jar. This is very convenient for
java developers to just download the jar, include in classpath, and using
the library, components and feature right away in their web application in
pure java. Furthermore the castafiore framework itself is very lightweight
with just 2 libraries and 1 web.xml entry. Even if the java developer is
not using castafiore in his project, he should find it easy to just drop
the 2 libraries + web.xml entry in classpath and start using it right away.
Very practical.*


   Load external resources like css and javascript lazily and efficiently
   only when needed.

   Loading of external resources can be done eagerly if the API user wish

   The framework does not own the whole page. Meaning that an application
   created with the framework can be used in an already created page. This
   allows API developer to use the framework only for very specific purposes
   like for example a dynamic table, while at the same time using other web
   framework like struts for the other sections of the application.

   Although a whole application can be created using pure java, the
   framework should be able to integrate templates.

   By default, there should be 100% separation of logic and presentation.
   Meaning that the API user should be able to take an html template, and
   dynamise it without needing to add any modification in the template.

   On the other hand, if an API user is more script centric, he is able to
   write groovy template, jstl templates or any other template engine.

   The API user should be able to easily use any template engine he wishes
   easily and naturally.

   Event model is in 3 phase. Client-> server->back to client. API user
   should be able to write events in java that starts executing on the
   browser, then goes on the server if he wishes, then continue executing on
   the browser. e.g. We should be able to add an event on a button that starts
   by executing some javascript codes, then take some parameters and execute
   codes on the server, then continue back with some parameter from the server
   to execute some more javascript codes on the client. This technique if used
   skillfully helps to create very smooth application that constantly
   communicates with the server without any flicker

   Support for websocket when the browser supports it.

   Support for HTML5

   Same API to write SVG applications.

   Same API to write html5 canva application.

   Support for browser back button

   Crawlable by google crawler

   Ultimately, the framework will come with a very rich set of re-usable

   Handle browser quirks

   Built in validation


The initial development of castafiore framework started back 3years ago by
Kureem Rossaye. Later it was mature enough to be used in production. A
whole web based platform was created. It consists of applications like
Inventory system, CMS, DMS, account system, organization management system
and also an advanced WYSIWYG online application builder. Many websites
ranging from simple catalog website to advanced e-commerce website were
also created using the framework.

Now I wish to donate this framework to the ASF in the hope to build a
community and see it strive

While there exists many web frameworks, there are very few that address all
the requirements at the same time. There is a need for a web applications
that at the same time can free user from javascript, html and css and at
the same time easily integrate them when needed. There is also the need for
a web framework that at the same time can be server centric and client
centric. For example, the front-end of a web site should be made client
centric and the back end server centric. While the whole application can be
written in java, the web framework allows to create a whole application
using traditional methods like html css javascript and page oriented
framework like struts or spring mvc and at the same time implement only
very specific parts using the framework.

Today many javascript library providers and making their libraries
“java-able”. e.g. SmartGWT or extjs

They are using GWT for this purpose. Writing custom components with GWT can
be extremely complex, error prone, difficult to debug and stabilize. Not
mentioning the compilation nightmare. And GWT is exclusively client
centric. Connection with the server is done exclusively via web services.
On the other hand, castafiore framework helps to make javascript libraries
“java-able” very easily. It is easy to debug and stabilize components since
there is no such thing as compiler to generate javascript.

The framework is built upon jquery. Indeed jquery is an excellent
javascript library. The framework basically acts as a thin layer over
jquery. The result is a very simple and intuitive api which helps to write
highly dynamic applications with lesser code. Just like jquery.

The 3 phase event model helps to bring the server very close to the
browser. Meaning that with the same API, it is easy to interact with the
browser and interact with the server. This helps to create very smooth
running applications and at the same time interacting with the server and
progressively render new components.

Thanks to the framework we will be able to harness the new HTML 5 api like
websocket, workers, storage system, canvas and others using pure java. This
is pretty exciting.

And hopefully, thanks to the ease at which we can integrate js libraries as
a castafiore components, we will be able to use already mature js libraries
in our java codes and interact with the server easily
Current Status

The rendering engine of the framework is completed and is being used in
production. A large set of components are also being used. The javadocs and
documentations are 90% completed. However there are many components that
need to be stabilized and of course, there is the need to create more
interesting, useful and sexy components for the pleasure of every

We need to create a good set of demo and sample codes

There is also a need to create a website where contributors can publish
their custom components together with their license and demo

I intend to donate the WYSIWYG application builder to the ASF and host it
online. This will be used as a sandbox or even can be used to create custom
components and publish them online itself, without the need to download or
install anything. I believe that this will help javascript library authors
to make their libraries “java-able”. To attain this objective, we need to
stabilize and increase security level on the application.

By submitting this incubator proposal, we’re expressing our intent to build
a diverse developer community around Castafiore that will conduct itself
according to The Apache Way and use meritocratic means of accepting

Castafiore is actively being developed and maintained within Archnet Ltd by
myself. By open sourcing it, I hope to attract contributors and build a
vibrant community around the project. I will do my best to provide all
necessary documentation and helps as swiftly as possible to help anybody
interested in contributing on the project.
Core Developers

Castafiore is currently being developed by only Kureem Rossaye

The ASF is a natural choice to host the Castafiore project, given the goal
of open sourcing the project and fostering a community to grow and support
the software.

Castafiore is a web framework tested and developed on apache-tomcat and
websocket features uses implementation provided by tomcat7
Known Risks Orphaned Products

There is currently one single developer for this project. However, this is
the main reason why I want to host this project to ASF in order to create a
community in order make the project less dependent on only myself. I also
express my intention to provide all necessary help and documentation to
help those interested to get started with the project.

Every aspect of the framework will be heavily documented to give clear
understanding of the rendering engine in order to help anybody modify,
enhance it.

Furthermore, the framework is being used in production in my company
Archnet ltd and has been deployed in several companies in Mauritius.
Inexperience with Open Source

Indeed, I have low level of experience in open source and has never
contributed in any opensource, although I have always wanted to do so.
However, by working with our mentor and the Apache community I believe I
will be able to conduct myself in accordance with the Apache Incubator

 Homogenous Developers

Actually there is only myself who is developing this project. This is
actually one of the reasons why I want to submit this proposal. In order to
be able to attract developers from various countries and companies. As I
have already mentioned, I will be dedicated to provide everything required
to help get started with contributing on this project.
Reliance on Salaried Developers

I am the sole developer of this project. I am the director of my company,
Archnet ltd. So there is no reliance on salaried developers for this
 Relationships with Other Apache Products

The project is a web frameworks that has been developed and tested on
apache tomcat. Furthermore, the websocket feature actually uses exclusively
the implementation provided by apache 7

 An Excessive Fascination with the Apache Brand

While we respect the reputation of the Apache brand and have no doubts that
it will attract contributors and users, our interest is primarily to give
Castafiore a solid home as an open source project following an established
development model. We have also given reasons in the Rationale and
Alignment sections.

Project documentation exists and will be update online soon
Initial Source
 Source and Intellectual Property Submission Plan

All the codes are available online on github.

Since I am actually the only developer on this project, it is very easy for
me to change the license to whatever license that best suits the ASF.

 External Dependencies

Castafiore depends on spring framework and commons-fileupload. They are all
Apache compatible.
