Open Geocoding data in Poland

[m_k]

So, I would like to ask if any of you know of such data (often based on cadaster data) or of such developments in Poland ? Any hints or links would be welcome.

We (Geo-System) made a geocoding service that uses address data from over 400 gminas (municipalities) in Poland. What's important - these data are official, the most current and continuously updated.
You can see a map of our services here http://punktyadresowe.pl/ , there is also a description of the geocoder ("Usługa lokalizacji"; unfortunately only in Polish), and here is a sample query: http://punktyadresowe.pl/lokalizacja.php...format=xml
