Hi,

I want to remove a long list of tags from the builtin-tag-list by different actions. The advantage is that specialised styles that do not need these tags are faster and do consume less memory.

== Tags that are no longer used ==

Tag: osm:id There are only two references in mkgmap source code: HighwayHook sets this tag and StyleConverter that reads this tag. I think this is not an OSM tag but a tag set internally by mkgmap. If so we should rename it to mkgmap:osmid. Any objections?

Tag: openGeoDB:postal_codes I haven't found any references in the source code. openGeoDB workout have been removed with locator branch merge.

== Tags that can be moved to style handling ==

I am thinking about moving some static coded rules (e.g. name of a POI street is taken from tag "addr:street") to the style system as it has been done with other location items: mkgmap:street!=*& addr:street=* { set mkgmap:street='${addr:street}' }

This has two advantages: 1. Speed improvement for styles that don't use this information. (Marko: this should help you with your need for speed improvements for special styles)

2. More flexiblity: If someone likes to use different tags for a POI street name it is easy to configure that.

Possible downside: * Little more memory requirement for styles that use address information

The tags to be changed are: addr:street addr:housename addr:housenumber addr:phone (is currently not used in mkgmap) phone is_in

== Tags that are used only if --route is set ==

I am not sure if that's correct. Can someone please confirm that?

I would certainly agree with you on the addr: tags; the way it is currently done internal to the mkgmap code is a little confusing and it would be much more flexible if the address treatment was moved to the points style file.

Not sure about addr:phone though - isn't this deprecated and instead phone=* is used to fill the telephone field in the address form?

Just my two fils,

Charlie

I believe that phone=* is being replaced with contact:phone, just like url is being replaced with contact:website. I guess we should support both.

Ok, I will commit phone=* only. If you think that contact:phone should additionally used that you can add that later on to the style. WanMil
