Adding a picture and potentially a short description field to Asset and Participant objects

[xamcost]

Hi there! I am opening this issue to suggest two things:

1. the addition to the Asset and Participant object of a picture field, which would be a url pointing to an image. The idea of this is to enable them to illustrate an Asset or Participant display in the marketplace with a logo. It is a low hanging fruit and would make the marketplace more appealing.
2. the addition of a short_description field in the Asset object, which would just be text. Its goal is to be a one sentence summary of what should be in the longer description field. This is to enable prospective consumer to have a quick overview of the asset in the offering.

I suggested adding these fields in Asset, but if you think it fits better elsewhere, such as in AssetProvision, let me know.

Hi!

I agree with point (1). We could add the foaf:img property to the ontology as part of the Participant class. This field could be recommended but not mandatory.

The same applies to the short_description property. A non-mandatory property could be added to the ontology. However, TBH, I’m not that keen on adding “duplicated” fields, as they introduce an additional "burden" for users. While I understand the reasoning behind displaying such information in the GUI, as a provider with multiple assets, I’d likely avoid adding two descriptions per asset. That said, as mentioned, we can always add it as a non-mandatory property.

If @telsaleh agrees, we update the ontology with those two properties.
