[request] I would like to ask for agentcard metadata

[jpandrade30]

This is a great project, thank you all for your effort. May i ask for metadata in agent card? Sometimes the information that we can provide on descriptions can be not enough, some metadata would help in such cenarios. Again, thank you all for all the effort being made in this project.

Firstly, I think this is a matter regarding the A2A protocol itself and not specifically this particular Python implementation.

It sounds like you want the agent card to contain structured data that is specific to your use-case. Here are a few other ideas:

1. Perhaps you could define an agent extension to cover this use-case specific functionality? This goes in the agent card 'capabilities'. The AgentExtension model contains a params field that is dictionary of arbitrary values, so consider whether this might meet your needs.
2. Although the description is intended to be human-readable, you could encode some structured data into it. JSON or YAML would be obvious choices.
3. You could make the documentation_url point to a resource from which the structured data could be fetched.
4. There are various fields in an Agent skill that could be used to hold structured data with a little imagination.

Apologies for the confusion! I thought I was in the A2A protocol repository rather than the Python-specific one. I should have double-checked before commenting.
For context, I'm currently using the second approach (including not only the description but also the expected format). I suggested this to simplify implementation, though I realize it may not make sense within the broader A2A protocol context.
Thank you for your patience!
