Future versions of this document MAY introduce additional message-identifying optional parameters. For example, hypertext messages could be identified by meta information in their HTML headers. Messages could also be searched for, using different methods than the regular expressions.
However, it is safe to discard unknown optional parameters of area URLs, though programs interpreting Fidonet URLs SHOULD probably warn their users if an unknown parameter is discarded and when such a warning is appropriate.
7.2.2. Encoded objects within echomail messages -+---------------------------------------------
It is possible for a Fidonet echomail message to contain one or more binary objects, encoded to appear in text-alike lines of characters. Possible methods of encoding include UUE, MIME (RFC 2045-2049), "data:" (RFC 2397), etc.
An echomail message MAY contain several objects, which MAY be encoded in different manner. On the other hand, an encoded object MAY span several Fidonet messages: for example, each of those Fidonet messages MAY bear a section or two of UUE, and the whole bunch of sections is needed to decode a file.
7.2.2.1. Names of encoded objects -+-------------------------------
This subsection is informative.
Most of encoded objects within echomail messages are named.
The name of a UUE-encoded object usually appears within "begin" and/or "section" line of UUE codes.
The name of a MIME-encoded object usually appears within either the "Content-type" header (in its "name" section) or in the "Content-disposition" header (in its "filename" section).
RFC 2397 "data:" does not specify an object name; however, the hypertext object populated by that data MAY be named itself, via "id" or "name" attribute of its tag.
7.2.2.2. How the designated object is determined -+----------------------------------------------
If the <object-path> of an area URL is not empty, then the URL designates either an encoded object as a whole or some inner part of such an object. Abstracting from this inner details, the whole object is called "the designated object" in this subsection.
If the <object-path> of an area URL is not empty, then its <object-name> MUST also be non-empty by definition, and it specifies the name of the designated object.
However, the echomail message base (of the area given in <areatag> section of the URL) MAY contain more than one object of the same name. It is therefore important to define what object is considered "the latest".
Among those messages that contain objects of the same name (or just parts of those objects, e.g. UUE sections), there is the latest message. If that latest message contains only one of those objects (partly or as a whole), then that object is the latest one. If that latest message contains parts and/or whole encoded images of more than one object of the same name, then the object whose complete encoding or just the last section of encoding (last among its sections contained in this latest message) appears nearest to the bottom of that message (farthest from top) is the latest object.
How "the latest message" itself is defined is beyond the scope of this document. It MAY be the latest received, it MAY be the one with the most up-to-date creation date, etc.
The designated object is always determined as the latest one among those of the name given in <object-name>.
Fidonet browser software MUST ignore objects which have such encodings that browser can not decode; the designated object MUST always be the latest of only those ones of the given name that are able to be decoded from the echomail message base.
If one or several message-identifying optional parameters are present in the optional part of the URL, then the designated object is the latest one among only those decodable objects of the same name whose complete encoding (or just a section of encoding) appears in one of the messages identified by the optional parameter(s).
7.2.2.2.1. Possible applications -+------------------------------
This subsection is informative.
As the <object-name> always designates the latest object of the same name, it is possible for "area://" URL to designate an object that is updated by means of Fidonet echomail area transport. Such objects MAY update daily (as in a weather forecast), weekly (as in a nodelist statistical report), etc. That's how Fidonet may easily serve dynamic up-to-date content. And if some URL is intended to point to an older static version instead of the up-to-date dynamic one, then an optional message-identifying parameter (if matches just a single message) is always able to ensure that.
If several nodes have write access to the same echo area, and it is not possible to rely just on the latest object of the same name, then "from" parameter can be used to ensure that the trusted origin is chosen.
As any Fidonet browser software MUST ignore objects which have such encodings that browser can not decode, it is made possible to include several alternative versions of the same object (encoded differently), even in the same one echomail letter, provided that the names of published object versions are all the same. The browser will happily pick the encoding it understands. For example, someone may post both UUE (for GoldEd+) and RFC 2397 (for Gecko) versions of the same icon.
