Implement a function to determine if two occupancy tags are compatible and which one is the more specific
After introducing the more detailed occupancy tags to taxonomy-lib, a function is needed that determines if two occupancy tags are compatible and which one is the more specific. This procedure should follow these cases (here presented in examples):
| Building tag | Asset tag | Return value |
|---|---|---|
| COM2 | COM2 | COM2 |
| COM | COM2 | COM2 |
| COM3 | COM2 | None |
| IND2 or IND | COM2 | None |
| COM2 | COM | COM2 |
| RES2A | RES | RES2A |
| RES2A | RES2 | RES2A |
The basic principle is that if one of both tags is a substring of the other (or equal), the two tags are compatible and the longer one is to be used as return value.
