@rhysrevans3 This pr looks really good. We have just been in the middle of adding opensearch support. Do you have any experience with opensearch?

[rhysrevans3]

@jonhealy1 I've added some more tests but realised the current version of stac-pydantic the api is using doesn't allow a null datetime field. To update to the latest version of stac-pydantic will require changes to both stac-fastapi and stac-fastapi-elasticsearch. I've made the changes to stac-fastapi in this pull request and am working on the changes to elasticsearch. But I think this pull request will have to wait until they're merged.

I don't have any experience with Opensearch but am happy merge main's changes into this branch and try to add this functionality to the opensearch parts.

@rhysrevans3 Any new thoughts? Hopefully we can merge this soon.

@jonhealy1 update on this pull request:

• I've added the extended datetime functionality to the opensearch code.
• I've added some extra tests to meet all the cases I can think of.
• I've added some comments to explain the database logic.
  Some of the tests I've added are failing as the current version of stac-pydantic doesn't allow the datetime field to be null. So I'm still waiting on the fast-api pydantic v2 pull request to be merged

Hi @rhysrevans3, the pydantic v2 is merged now into main via stac-pydantic if you want to have another look at this. Cheers.

@jonhealy1 it looks like that stac-pydantic still won't allow a null datetime I thought the validator would allow this but I think the typing stops it. https://github.com/stac-utils/stac-pydantic/blob/main/stac_pydantic/item.py#L31-L58

Good news is there appears to be 3 pull requests that will fix this:
stac-utils/stac-pydantic#116
stac-utils/stac-pydantic#131
stac-utils/stac-pydantic#135

Sorry for the delay in this.

[jonhealy1]

Hi @rhysrevans3 - no problems whatsoever - thanks for staying on top of this!

[rhysrevans3]

@jonhealy1 looks like this might be finally ready to merge. :)
