Currently we have 3 types of ApiObjects. There will be more in the future.

• InstagramTags
• InstagramLocations
• GetGlueObjects

Properties should have many API Objects and API Objects should have many Properties. (i.e. an InstagramTag of "#sxsw" could belong to multiple Properties. But, a Property could have "#sxsw", "#oblivionsxsw", and "#sxswmusic" as its InstagramTags.)

We want to avoid having to have a join table for each type of ApiObjects.

Each type of API Objects needs to be its own table with its own attributes and a Property needs to be able to call on all of its API Object by type. Property.get_glue_objects, for example.
