Hi alto-cdni authors and WG,

According to the discussion during our interim meeting today, I just have
two comments:

1. It is not a good idea to introduce a new Map service for CDNI FCI. There
are two reasons:

  a) CDNI FCI is not a map but an information base.

  b) If we really want to use a Map service to provide the CDNI FCI, the
property map is already enough. If we want some features which the property
map cannot provide, I think a new Map service can neither provide them.

2. I hope some author can provide a concrete example or use case to show
the property map is not enough for CDNI FCI. If we really have the
motivation, I think a new service is required. But it should not be a Map
service.

Just my 2 cents.

Thanks,
Jensen
