contains the character "/" in its literal meaning, the character MUST be encoded.
If an <areatag> corresponds to an echomail area which is not available on the system, the URL MAY be treated as equivalent to areafix:<areatag> and the user MAY be asked whether he wants to subscribe.
If <object-path> is empty and <optional-part> does not contain message-identifying parameters, the area URL designates an area as a whole.
When such a link is used (clicked, followed), an echomail browser MAY open a sorted list of echomail messages present in the given area, or a threaded list of replies. This depends on user settings of the browser.
If <areatag> is empty, the <object-path> MUST also be empty; such URL leads to the list of available echomail areas, also known as the arealist.
If one of the message-identifying optional parameters is present in the <optional-part> of an area URL, then
area://<areatag>?<optional-part>
no longer designates the whole message base of the given area, but only the message specified by the value of the message- identifying optional parameter(s).
The "msgid" optional parameter is used to designate a single message in the given message base. The value of this parameter is the contents of MSGID kludge of that message, without the leading "^MSGID: " string.
MSGID kludges are defined in FTS-0009 and serve well as unique message identifiers of echomail messages.
Note that the "msgid" optional parameter MAY designate some message that is not present in the current echomail message base of the given area. In this case, a Fidonet system MAY ask its uplink for a rescan of such an area, or use some external archive of Fidonet echomail messages, or try some other means of getting the desired message. The designated message is not available until this actions bring the desired result. And programs interpreting Fidonet URLs SHOULD NOT discard "msgid" and pretend that area://<areatag>?<optional-part> designates the whole area if the desired message can not be accessed immediately.
The "mid" optional parameter is used as a shorter equivalent to the "msgid" parameter. If the optional parameter "msgid" is not present in a given URL, the value of "mid" parameter MUST be taken instead the value of "msgid", provided that "mid" is present.
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, if a unique enough search string is provided.
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 -+----------------------------------------------
