[oslc-ArchMgmt] OSLC AM General Meeting 15-August

[James Conallen]

Hi Pete,

Thanks for your comments.  I'll respond to a few of these if I can.

I've added a description for oslc_am:order. This was just an omission on my
part.  We discussed the nature of the property last time.

You are absolutely correct we have not proposed any coordinate system as of
yet. This needs to be done.

The justification for layers comes in part from some behavior we have in
Rational Software Architect which does support layers on individual
diagrams, and most importantly this behavior is for the most part
independent of the semantic meanings of the views participating in the
layer.  An RSA user can select arbitrary views in an RSA diagram and add
them to a custom defined layer.  These layers can be selectively hidden.
The main justification for layers in general is to provide a means to help
simplify overly complex and large diagrams.  I should also note that AM
providers are obliged to support layers.  If the service provider already
does so this specification just describes how it can be presented to the
client for use.

We have discussed a lot about the usefulness of layers with SVG.  As you
point out diagrams leveraging SVG have many architectural advantages.  Many
of these overlap with the capabilities provided for by this Diagram
resource specification (i.e. hot spots and click through).  In general we
feel that most of what the Diagram resource provides is for raster images
and diagrams, not SVG.  We can not guarantee, nor can we require that
diagrams only be rendered with SVG.  As a result we offer this resource
specification to provide that information.

Oslc_am:order has no description.
What coordinate system are you assuming for diagrams? Without a defined
system Diagram Area is somewhat meaningless.
Not sure the Usage Scenarios justify either of these anyway.

I’m also not clear on the justification for Layers – I cannot think of any
modeling tool that allows a single diagram to be layered in any way.

The Usage Scenarios ignore (and mitigate against) the use of SVG – which is
a common (and preferred – due to its compactness, quality and extensibility
e.g. support for popups) format for diagrams from modeling tools and is
natively supported by all browsers (except IE8 and earlier).

      Ø  This should be a <img> tag with the URI of the diagram resource.
      Ø  …
      Ø  For HTML documents the user can simply insert a <img> tag with the
      src attribute set to the diagram resource URI.
<img> is not always appropriate for images: see
http://www.w3schools.com/svg/svg_inhtml.asp for SVG options

      Ø  HTML has a <map> tag that allows the user to click in a specific
      area of an image, and the browser will navigate to that page.
Again this is not appropriate for SVG which can embed external links
directly

Regards
Pete

If you have time please look over these two documents before tomorrows
meeting.

http://open-services.net/bin/view/Main/AmDiagramResource
http://open-services.net/bin/view/Main/AmPredefinedQuery

We will discuss these topics.
