Good day tcgcwaypoint. Welcome to OpenStreetMap and thank you for your very detailed contributions at Tangub City Global College. 

In OSM we have a quite complex tagging system with specific established tags for almost every object that can be mapped. For compatibility it's important to stick to these tags whenever possible. 

The OSM wiki has descriptions and definitions for most of these tags. For example here you can find all you need to know about indoor mapping like what you attempted at TCGC: https://wiki.openstreetmap.org/wiki/Simple_Indoor_Tagging

Instead of pathway you can use highway=service for driveways highway=footway for outdoor pedestrian paths, indoor=corridor for indoor paths.

For rooms the correct tag is indoor=room + room=office/toilet/classroom, etc. For buildings there are specific tags to describe the function, e.g. building=college, building=sports_hall.

Hope this helps and don't hesitate to ask if you have any questions!

Best regards,

Timmy
