Query Product
The following presentation contains a short gap analysis regarding STAC and the AIP of the LTA service:
This table focuses on product properties that should be exposed by AIP instances and that are not currently backed by STAC Core or extensions.
| Property Name | Possible values / Example | Common | Comment | Proposed solution |
|---|---|---|---|---|
| Online |
| Order extension field order:status:
| ||
to be stated in the ICD : Offline : item with no assets Online : item with assets |

Process definition
TODO : add a table on Process definition with input and output parameters (as a requirement)
Bulk Product Retrieve
The bulk is defined by a list of products or query filter parameters and a batch size
1st level assumption: not "as is" in the OGC standard.
Ideas :
- Create a specific Process for "Bulk Create Request".
- query filter parameters : the process parameters == filters
- list of products : one parameter as a list of product IDs
- BatchOrder List Request : is the result of the "Bulk Create Request" Process
- Create a specific Process for "BatchOrder trigger"
Good to simplify the current way to do bulk (many batch orders to trigger !!)
Trigger all the batches automatically
→ offer the user to automatically execute the batch orders or not (as a parameter of "Bulk Create Request")
