Hello Martin and ALTO WG, Thanks again Martin for your thorough review and discussions that allowed to improve the document and enrich the capabilities of this extension.
This new version addresses the comments in the AD review and is available at https://datatracker.ietf.org/doc/html/draft-ietf-alto-unified-props-new-18 You may check the diffs here https://www.ietf.org/rfcdiff?url2=draft-ietf-alto-unified-props-new-18 The main updates: - remove unused and unclear terms and clarifies text in many places, - Filtered Property Map (FPM) queries now allow empty lists of entities and properties. Empty lists are interpreted as representing the full set of entities and properties. - put tables and text in coherency in IANA sections 12.2 and 12.3. Though due to lack of space, only added a column "mapping to ALTO address type" in Table 2. Some text on the security issue item referring to relevant sections was added in the introduction of section 12.2 and 12.3 The key updates were added in section 8 "Filtered Property Map". (FPM) They address the question on: how a Client can obtain the list of entityIDs that can be used as input to a FPM without having to download a full property map. The FPM query input format and response have been updated accordingly. - In Section 8: a paragraph explains why this is useful for a Client - In section 8.3 Accept Input Parameters: the format of query object ReqFilteredPropertyMap is revised and explained to support this. The property member is optional. - In section 8.6 Filtered Property Map Response: --- an error case is added when input member "entities" is absent --- text explains how, when the "property" member is absent in the query, the Server returns an empty value for the queried entities. We hope the updates are meeting the review expectations.
