How to create a map where you can display information about buildings or highlight buildings that match the given criteria (OSM tags + your own)?

Question

OpenStreetMap

You need to take an OSM map of a particular city, save it separately, add your own tags to buildings.
Make everything available online, with the ability to display information about it when you click on a building. Implement search by building tags. The search result is a specific building or buildings highlighted in color that match the query (you need to color the building polygon).
By what means is it possible to implement this?

Answer 1

To output a map (OSM layer + your own vector layers on top of it) Leaflet can be used . Very handy thing, there are many plugins.
As for the search, I think I'll have to write separately. You can use Backbone.js or another framework. Well, it depends on the number of buildings - if there are a lot of them, then you should take care of storing data and searching for them in the database on the server.
