Re: [Hypercontent-users] About_hyporconent2

[Alex V. <av...@co...>]

HyperContent 2.0 is not ready yet for use in production - while much of 
the code that is there is stable, I'd like to keep open the possibility 
of some API changes between now and the release.  As I have mentioned 
before, HyperContent 2 is backwards compatible with web sites built in 
the current version, so I continue to encourage use of HyperContent 1.4 
until 2.0 is released.  If you need to build a web application today, I 
would encourage you to consider something like Spring.  For building a 
static web site without form handling, HyperContent 1.4 is sufficient.
	As a framework, HyperContent 2.0 will offer a great deal of benefit in 
terms of establishing pipelines to generate a presentation layer bound 
to some form processing; however, it provides no database specific 
utilities, unlike Spring.   Berkeley DB is only used currently as a 
content caching mechanism, so that the output of a complex pipeline can 
be reused.  I have considered an IFileSystemManager implementation 
based on BerkeleyDB, but this is not currently a priority, as the 
existing repository implementation is stable and performs well.
	To use  MySQL or any other data source in HyperContent 2.0, there are 
3 possible levels of integration: an IFileSystemManager implementation 
would allow for a complete, generic repository to be implemented in a 
DB.  A custom pipeline stage could be used to load data from the DB 
into objects that could be rendered via Velocity to an HTML form, and 
bound to a FormProcessor which could persist changes back to the DB. A 
subclass of FileAsset could be used to load some data from the database 
based on the contents of a file in a normal HyperContent repository.

I have not analyzed what would be involved in a data conversion between 
HyperContent and Cocoon.  I have no plans to perform such an analysis, 
but if you would like to investigate, that information may be of some 
value to the community.

HyperContent 1.4 uses uPortal groups and permissions to evaluate 
whether a user can view or edit files.  When a user is a Portal 
Administrator, this logic is bypassed to always respond "yes".  Thus 
there is more processing involved in displaying file-browsing screens 
for non-administrators.  However, uPortal does cache permissions 
information, so the performance hit should not be too noticeable.  It 
may help to make sure you have indexes on the UP_GROUP_MEMBERSHIP and 
UP_PERMISSION tables.
