[mapguide-internals] RESTful Ramblings of a Restless Lunatic

[Haris Kurtagic]

Truth is the most parser implementation will encoded everything beside
digits, letters and - _ . ~ ( or very close to that ).

Also I don't understand what you mean about looking at [ .
I think if we wrote it as [ character or user type it as "[" then it
will appear as "[" character in string, how browser will send it encoded
or not encoded is than another thing...

The one that is not encoding it is behaving illegally :)

The BNF-like description section of the spec contains the following
(fairly clear) wording:  The "national" and "punctuation" characters do
not appear in any productions and therefore may not appear in URIs. 

And national is defined as:  { } | [ ] \ ^ ~

I see your point about encoding/decoding I guess, but I'd hate to use a
separator that couldn't be easily distinguished in the URL string.  It
would make troubleshooting difficult.

Regarding [ ] characters, two major browser's behavious differently, IE
and Firefox, one will encoded one will not.
Any how , those characters are interpreted normally by browser and
server.
Regarding encoded I believe that at the end when we will develope all
functionality ( sql queries, spatial filters, MapGuide identifiers,..)
REST URI will certainly not look "nicely" to human eye.
I think that is something which is not that important and after
implmenting RESTfull principles beside first-entering URI, other URI's
will not be important to user or application.

I think it is important that URI parser undoubltly and quickly can
identify resources in URI path, but that doens' mean it is nessecceray
[] combination.
I saw some suggestion's to use ! in path to separate filter part.

You're absolutely right Bob (well, from my reading anyway), reference
here:

http://www.w3.org/Addressing/URL/uri-spec.html

The character doesn't really matter to me, but I don't want to see it
being encoded.  Basically, we just need a common way of separating the
resource from the filter.

Looks like the only open/close option is standard parens (), but there
are a lot of single delimiter such as $ or @

To avoid problems, it would be nice if we could choose a delimiter that
is not a valid resource names in MapGuide if possible.  Any suggestions?
Now you're going to tell me that MapGuide allows any URI-valid
characters :)

I just did some checking and the way I read the URI specification (RFC
3986) square brackets [ ] are not valid within the path portion of a
URI. Hence they would need to be encoded as %5B and %5D.

Someone else should probably look and validate that. I decided to check
because I have never seen brackets used within a URI path before, and
non-standard syntax always raises a flag in my head.
