<scribe> Scribe: Karol_Szczepanski

Consider extending Hydra to handle non-RDF payloads

t_pluskiewicz: I had some discussions and the only thing that is needed is the first snipped after the proposed solutions

https://github.com/HydraCG/Specifications/issues/199

t_pluskiewicz: #199 replaces range of the hydra:expect with rangeIncludes

Karol_Szczepanski: will be there any harm in having both range and rangeIncludes?

t_pluskiewicz: whatever will be there, will be considered hydra:Class

Karol_Szczepanski: this is a breaking change
... I've suggested replacing a hydra:Class with hydra:Resource leaving range predicate

https://github.com/HydraCG/Specifications/issues/199#issuecomment-512552384

t_pluskiewicz: what about having both, range of hydra:Resource and rangeIncludes with more hints

serialseb: I'm thinking about a generic browser console, when browsing, how will it work?

t_pluskiewicz: a completely generic browser is ultimately an excercise gowing towards utopia
... generic client should support at least those of the rangeIncludes values provided in the spec

serialseb: I may accept an event but that specific server will accept it in turtle format
... I think content negitiation shoulld be a topic for another call/spec modifications
... I think operation expectation and what can be actually sent may be somehow different

<scribe> ACTION: Karol_Szczepanski will create a PR with range of the hydra:expect downgrade to hydra:Resource and introduce rangeIncludes with hydra:Class

t_pluskiewicz: we shall start thinking aobut an esxtension which will come with those features missing

Karol_Szczepanski: I'm worried that this will end up with a core vocabulary unusable and several extensions that won't fit to each other

<scribe> ACTION: serialseb will provide raw use case scenarios of what may be needed regarding non-RDF payloads and content negotiation

<t_pluskiewicz> TemplatedLink cannot formally have supportedOperation

<t_pluskiewicz> https://github.com/HydraCG/Specifications/issues/197

Return to recently discussed PRs

<scribe> ACTION: Karol_Szczepanski will take care of #197

Discuss PRs in Example API repository

<t_pluskiewicz> https://github.com/HydraCG/api-examples/pull/8

t_pluskiewicz: I've sidestepped the issue as type entailing is quite complicated when you go deeper

Karol_Szczepanski: indeed; what Heracles.ts does not is a simple range/domain entailing and possibly I own't go any deeper
