Subject: Re: [uddi-comment] UML diagrams of UDDI schemas v2 and v3

Hi Claus,

I will provide a longer explanation later today or this weekend and will add
some additional diagrams for datatypes.  Until then, see the attached
"datatypes" diagram (in both svg and png formats, for convenience to others).
This is not a complete list of datatypes, but covers those you mentioned.  When
no namespace is provided on this diagram, it is the UDDI namespace (this
information is within the model definition).

As a general note, the UML _model_ reverse engineered from the schema has much
more information in it than the _diagram_, which presents one view of the
model.  I intentionally omitted some detail to avoid clutter, and other
metadata within the model is difficult to show in a diagram.  Other metadata,
such as the <<XSDattribute>> stereotype on class attributes is also omitted in
the businessEntity diagram, but is included in this datatypes diagram.

In the businessEntity diagram, note that an attribute, e.g. "description" had
the datatype, also called "description".  The attached diagram show expanded
detail of these datatype definitions, hopefully answering your questions.  I
will look for other ways to provide more of this information in the main

As for catagoryBag, that class definition contains a property ("tagged value"
in UML spec terminology) which specified that:

Again, I will find a way to include this in the main diagram, but the detail is
included in the UML model.  This reverse engineered model can be saved to XMI
format and imported into other UML tools, such as Rational Rose or Gentleware
Poseidon (and many others, but these are the ones I test with).  The diagram I
provided where 100% automatic layout.  If you import this model into Rose or
Poseidon, you can customize diagram layout and presentation, to the extent it
is provided by those tools.

Best Regards,
  Dave Carlson

The diagrams you generated seem very useful to me since they simply visualize
the schema's complexity.

Also, I think that it is reasonable to use a stereotype in order to specify XML
schema choices or complex XML schema sequences in UML (I don't have any other
idea on which UML feature could specify choices).

However, there are some issues I'd like to make you aware of:
- I am not sure why the businessEntity's UML diagram stops at the
instanceDetails level, which has a more complex inner structure than the
instanceParms element only.
- While the name, description, address and personName elements carry the
xml:lang attribute, this is only shown for the address element and it does not
indicate that the lang attribute is derived from the xml namespace.
- I was looking at the categoryBag structure over and over again, but it
doesn't seem correct to me. A categoryBag consists of a number of
keyedReferences and a number of keyedReferenceGroups where at least one
keyedReference or one keyedReferenceGroup must be provided within the
categoryBag. The
generated diagram states that at least one keyedReference AND at least one
keyedReferenceGroup must be provided.

Subject: [uddi-comment] UML diagrams of UDDI schemas v2 and v3

I've been working on tools and techniques for mapping XML Schema definitions to
and from UML models.  As part of this work, I've started to create a repository
of UML class diagrams reverse engineered from common XML Schema standards or
proposed standards.

For complete UML class diagrams of the core data model for both UDDI v2 and v3,
see this link:


It's very helpful to get a quick bird's eye view of the differences between
UDDI v2 and v3.  These diagrams are also complete and accurate representations
of cardinality and datatypes from the schema.

Similarly, I've created diagrams of the draft Universal Business Language (UBL)
schemas that have been used as part of that TC's design work.  I hope that
these diagrams of UDDI will be useful for both users of UDDI specs and the
designers in this new TC.

Note that the diagrams are in SVG graphics, so you need to have the Adobe SVG
reader installed in your browser prior to reading the diagrams.  This works
very similar to the PDF reader.  The above link includes a download link for
the Adobe reader.

Please reply with any comments or suggestions about how this can be useful to
the ongoing work of this TC.
