Do it as string. You can change it if you run into problems later.

My suggestion:
- String is key=value;key2=value2;key3=value3 and so on.
- Semicolons in keys or value are replaced by '%3B' before storing and
replaced back when reading. (from URL-encoding)
- ID's are NOT stored in the properties, since you want a fast access to
them. However, in GPX, they have to be transferred in <extensions>
sometimes.
- before sending in GPX, the string is translated into key/value pairs
within the <extension>. Example: <osm:property key="key" value="value" />
- Make it bigger than 256 chars! ;-)


Ciao, Imi.
