Use of "related" in a Concept

[Cliff Casey]

Hello,

While testing a new automated xAPI Profile validator, we noticed that there was a potential conformance issue in a number of profiles in this repo.

Specifically, the use of "related".

For example, in acrossx/acrossx.jsonld on line 252

{
"id": "https://w3id.org/xapi/acrossx/verbs/liked",
"type": "Verb",
"related": [ "http://activitystrea.ms/schema/1.0/like" ],
"exactMatch": [ "http://activitystrea.ms/schema/1.0/like"
...

According to spec, the "related" property MUST only be used on Concepts that are deprecated to indicate possible replacement Concepts in the same Profile, if there are any.

Below are the instances we found. In any case where we found an issue, either the referenced Concept was from another Profile or the containing Concept was not set as deprecated:

acrossx/acrossx.jsonld | line 252
activity-streams/activity-streams.jsonld | line 524
activity-streams/activity-streams.jsonld | line 1118
activity-streams/activity-streams.jsonld | line 1284
adb/adb.jsonld | line 73
adb/adb.jsonld | line 96

We wanted to share in case you were unaware of the issue.

Thanks,
Cliff Casey
