I want to follow up on BIP 21 (URI scheme), which I have recently
implemented in Armory and I have become a huge fan of it. But I've got
a couple gripes:
*(1) *What is the status & plans for supporting "bitcoin:" URIs in the
Satoshi client? My understanding is that it currently creates URIs, but
does *not* register itself with the OS to handle such links. Is this
accurate? This seems like a very high-value feature, and I'd recommend
that we consider it a priority -- I can't think of any other upgrade
that can improve usability so dramatically on the desktop.
After implementing it all in Armory, I wrote up a walk-thru
<https://bitcointalk.org/index.php?topic=79010.msg879804#msg879804>
recounting how I did the OS-registration in Windows and gnome-based *nix
systems. Perhaps it can give the Bitcoin-Qt devs a jumpstart on getting
it implemented. (and then I can get feedback about doing for generic
Linux and Mac/OSX)
*(2) *I need to understand better what the intentions were behind
"label=" and "message=". The way I understand it is that Bitcoin-Qt
uses and stores only address-labels, and no other transactional info is
stored in the wallet. As such, the "message=" field would be displayed
to the user when a "bitcoin:" link is clicked, but that message wouldn't
be saved anywhere.
However, I think, especially if a new wallet format is in the works,
that both should be supported: "Address Labels" *and *"Transaction
Labels". The real difference is that merchants can include things
Order#, purchase information, etc, in the "message" field, and then put
only their business name in the "label" field. This means that when the
user is looking at their address book, they see just the owners of the
addresses. When they look at the transaction ledger/history, they see a
full list of everything they purchased, prices, contact info, etc. The
distinction is much more important for persistent addresses, but still
important.
This is exactly how I did it in Armory, but if Bitcoin-Qt won't do it
that way, I should be promoting all important information be jammed into
the "label" field.
*(3) *How are the other clients implementing this? Do you make any
distinction between "label" and "message"?

It is already implemented for Linux (Gnome) and Windows, but there is an
issue with boost::ipc that crashed bitcoin at startup on windows, so it's
temporarily disabled on Windows.

Label is a label for the destination address, message is a freeform message
describing the transaction.
I don't think the message is currently stored in the Satoshi client. That
feature is somewhere on our way-too-long issue and todo list.
But I understand that you want to add transaction meta-data fields such as
contact information, bought items, item prices?

Bitcoin Wallet for Android currently ignores both fields. At least
temporarly displaying the transaction message is on my short-term todo list.

I don't want to add fields to the URI-spec, I just want to add them /to
the client/. To me, it is ideal to have separate strings for labeling
/addresses/ vs labeling /transactions/ -- i.e. different strings would
show up in the address book (owner info) than what shows up in the
transaction history (purchase info). I say it's ideal because that
concept seems to fit perfectly with availability of "label=" and
"message=" fields in BIP 21, but it won't actually work if Bitcoin-Qt
won't/can't do it that way.
For now, it seems that I should count on all important information being
in the /label/ field, since users creating URLs would have to assume
anything in the /message/ field will not be saved. Though I imagine the
message data will be /displayed/ after the URI is clicked, just not saved.
To expand the concept slightly further, it might make sense in the
future for users to populate the /message/ and /label /fields with lots
of data, using newlines. The first line would be used as a summary and
displayed in the address book and ledger. The extra lines would all be
displayed when the user opens up a details window. All of it would be
automatically generated by the merchant, and the purchaser would end up
with detailed documentation on every purchase they've made for zero effort.
