Subversion release 0.28

Subversion 0.28 has been released and there is an interesting article with the title "Subversion release 0.28 - the better CVS - also for Eclipse, Emacs, Tortoise and more" from Christoph C. Cemper.

I'm looking forward at Subversion becoming mainstream for open source projects!

A Compact Syntax for W3C XML Schema

The article A Compact Syntax for W3C XML Schema on by Erik Wilde presents an interesting alternative to the verbose W3C XML Schema while preserving the same semantic.
Here's an example from the article to give you an idea:

W3C Schema fragment:
<xs:element name="complexContent" id="complexContent">

<xs:extension base="xs:annotated">
<xs:element name="restriction" type="xs:complexRestrictionType"/>

<xs:element name="extension" type="xs:extensionType"/>
<xs:attribute name="mixed" type="xs:boolean"/>

XSCS (XML Schema Compact Syntax):
element complexContent extends xs:annotated {

( restriction { xs:complexRestrictionType } | extension { xs:extensionType } )
attribute \mixed { xs:boolean } }

That's definitely less verbose although I don't know if I like the curly bracket and the backslash that much ;-)

OWL - Web Ontology Language Candidate Recommendation

The OWL Web Ontology Language Candidate Recommendation of the W3C has been released on August 18th.

Reading a new book: Practical RDF

I started to read the new O'Reilly book "Practical RDF" by Shelly Powers.
It has about 330 pages and shows you the practical side of RDF.
I'm not a very fast reader, since I only read such books when I've got some time on the week ends or on holidays. Today I got to page 6 then I had to jump into the pool because of the hot weather ;-)

Talking about standardization

I had an interesting talk about standardization with my father-in-law Leopold Lasselsberger, who holds some important offices concerning biogenous fuels and wood combustion systems.
He encouraged me to take a closer look at the standardization efforts done by such consortiums like W3C, Oasis, IETF and others.
Let's see where this leads me to ...

Wedding and wonderful honeymoon

Yes, we finally married!

Originally Maria and I were afraid from this step as we both hate big celebrations. Nevertheless it was the most beautiful day in our life.
To some part that was due to the fact that we didn't want to have a traditional wedding. Instead we wanted to have it the way it fits best to us. I'm sure we hadn't got so much positive feedback afterwards if we followed every hint about how we should do it ;-)

Now some more infos:
We married on July 19th (the 25th birthday of Maria) at the registry office in Wieselburg (15:00) and afterwards (with some drinks and photos in between) at the church in Neumarkt (17:00).
Theb we had some time to talk to friends, relatives and neighbors while having a drink and something to eat.
After that we drove to the Mostlandhof, where we had an excellent dinner. This restaurant is located on a hill where you can overlook beautiful parts of the Erlauftal. The weather was excellent and we could enjoy a really beautiful sunset.

At about 24:00 we were taken to a quite new Hotel in Amstetten, called Exel, where we spent our wedding night.
On monday at 02:15 early in the morning a bus catched us and brought us to Venice (Venedig for german speakers ;-). There we got onto the ship Costa Classica where we had a wonderful one-week cruise: Venice - Bari - Katakolon/Olympia - Santorin - Mykonos - Rhodos - Dubrovnik (Croacia) - Venice.

I never imagined that our wedding could be so beautiful.
Here I'd like to say thanks again to the parents and grandparents of Maria for making us such a big present with the Hotel and the cruise.
