Subject: Re: [wsrp][interfaces] separate administration interface, requirements



Alejandro -

I do not agree with the requirement that we MUST have a separate
administration interface. Everything could be done reusing the current
concepts:
- if the consumer is able to do so it can just display the portlet in
config mode to let the portlet configure itself. This way the portlet can
present its configuration data in a convenient form and especially make
sure that the modifications the user makes to the data are consistent
- the consumer can also enumerate the properties AT RUNTIME and display
them in a property editor to the user (or use a console application for
this purpose). This is not very user friendly but possible. One problem is
that the consumer could not check for data consistency (e.g. verify the
data), but we can live with that.

So why do we need a separate administration interface. This only
complicates the standard.
Why would the consumer need to publish all its parameter (names) as
metadata if they can also be queried at runtime? This introduces
redundancy,

Carsten,

Thanks for you answer. I think we are not agreeing with the
requirements, let me rephrase things:

WSRP must have an administration interface for administering portlet
configuration and settings attributes.
A producer must provide metadata about the portlet configuration and
settings attributes.

Forcing the consumer to display the portlet to administer/configure is
too restrictive. Not requiring an administration interface and the
corresponding metadata will force the consumer to display the portlet
for its administration.

Do we want a consumer to be able to have tools (other than a markup
based ones) administer/configure portlets in a producer? For example,
command line tools or fat client tools.

Regards.

Alejandro.
