createdAt / modifiedAt incorrectly reported as invalid about context.orion-ld

[kzangeli]

True, those two "builtins" aren't getting any special treatment by orionld as of today.
Not sure what the broker should do if encountered with them ...
There are really only three options:

1. Return Error
2. Ignore them (as the broker sets these values itself)
3. Use them and let them override the builtin values.

From this issue I assume we will go with option 3.
Do we really want that?
I mean, the timestamps will be incorrect ...

PR #48 should fix this problem (option 3: builtin values are overridden)

From the specification:

5.2.2 Common members
The JSON-LD representation of NGSI-LD Entity, Property, Relationship, Context Source Registration and Subscription
can include the common members described by table 5.2.2-1.
Those members are read-only, and shall be automatically generated by NGSI-LD implementations. They shall not be provided by Context Producers. In the event that they are provided (in update or create operations) NGSI-LD implementations shall ignore them.

[kzangeli]

ok, I'll change what I implemented to IGNORE instead of override.
Makes sense, no probs

github closed the issue for me ... reopening

[kzangeli]

The issue should be fixed by PR #64
