Use the "finished" property of Job status.
When job completed, "finished" is
updated with date of completion.

Use the specific STAC property order:date. It requires

the 

the STAC item corresponding to product to order is

updated 

updated when the order is created

Automatic creation of Batch OrdersbulkCreateBatch orders processes are created 
in advance in the bulkCreate step
but not triggered. The client has to
trigger each of them for execution.

Batch Orders processes are not automatically created.

The client has to execute a new process called "batchOrder"
for each internally prepared/stored Batch order 

No concept of "process triggering" in OGC API;

 

only process execution.

It doesn't change anything in terms of number

of
queries

of queries to send by the client. 


Setting of FilterParam query parameterbulkCreateFilterParam property is a string with 
the complete criteria		FilterParam property becomes a array
of objects. Each object is a criterion for
product filtering

Less complexity on client side to define STAC query.

The query is built by the service and is

compliant
with

compliant with STAC Filter extension

keeping a string
BatchOrder query sub-stepbulkCreateThe bulkCreate step don't return the list 
of Batch Orders but the client needs to 
send another query to get them.		Job result of bulkCreate process contains
the list of batchOrders as an output parameter		simplification of workflow

Notification about asynchronous process completion:


credentials information

productOrder
batchOrder
bulkCreate		Provide notificationUsername and
notificationPassword parameters

Add following input process parameters: 

  • notificationUsername: The username associated with the
    Endpoint URI provided in the subscriber.successUri property of the
    execution payload
  • notificationPassword: The password associated with the
    Endpoint URI provided in the     subscriber.successUri property of the execution payload 
Open question: is reference implementation 
of OGC API - Processes able to build 
notification request with addiotional input 
parameters ? 
Notification on Subscriptions
The LTA service posts a HTTP query to a 
predefined callback URL 		The notification is sent asynchronously through a AMPQ
message broler  

More robust, especially if client's URL is irresponsive. 

However, this requires a overwork on client side.
