## Input Formats

|
|
At the core of OpenTripPlanner is a library of Java code that finds efficient paths through
|
|
multi-modal transportation networks built
|
|
from [OpenStreetMap](http://wiki.openstreetmap.org/wiki/Main_Page), [GTFS/GTFS RT](https://gtfs.org/documentation/overview/) and [GBFS](https://gbfs.org/).
|
|
|
|
In addition to GTFS, OTP can also load data in the Nordic Profile of Netex, the EU-standard transit
|
|
data interchange format. The upcoming EU-wide profile was heavily influenced by the Nordic Profile
|
|
and uses the same schema, so eventual support for the full EU profile is a possibility.
|
|
|
|
GTFS and Netex data are converted into OTP's own internal model which is a superset of both. It is
|
|
therefore possible to mix Netex and GTFS data, and potentially even data from other sources.
