[Freegis-list] geospatial web services help requested

[Christopher Jon Jursa]

Hello,

I am performing research in geospatial web services.  I have a few questions
that I was hoping some here could assist me.

1) I have read serveral documents on the topic but most of my research has
consisted of conference papers.  I am looking for some journal articles.
Does anyone know of any?

2) Does anyone have any good references (either conference or journal) that
deal specifically with chaining geospatial web services together?

3) Does anyone know of any UDDI directories with geospatial web services
available?

4) How does the standards from W3C for web services cooperate with standards
from OGC?  Do they compete?

Sincerely,
