OSCAR uses UUIDs in several places to express what kind of capabilities a client has and what features it would like the server to support. The nice thing about UUIDs is there does not have to be a central registry since they are unique when created. There are many websites and tools out there that will create a UUID. UUIDs are also sometimes known as GUIDs.

UUIDs are transmitted as 16 bytes of binary data; however in documents they are written down in string form like 09460000-4C7F-11D1-8222-444553540000.

At some point it was decided that full UUIDs were too verbose for common capabilities, so AIM uses both full UUIDs and what are called "short UUIDs" or "Short Caps". A "Short Cap" is really a UUID of the form 0946XXYY-4C7F-11D1-8222-444553540000 where XXYY is the short cap. A client receives short caps if it asserts the short cap capability. If a client does not assert the short caps UUID, it will get most caps in long form. Some APIs only take UUIDs In those cases the long form of a short cap should be sent.

Client and library developers should feel free to create valid new UUIDs, just do not create new "Short Caps". If developers would like to publish their UUIDs and what they mean, we will be happy to document them here.

Capabilities

Capability is a 16-byte array that represent specific ability of IM client (AIM or ICQ). For example there is RTF-capability meaning that client supports RTF messages. Each client has its own capability list and it use |SNAC(02,04) to send this list to server.      All native clients was built using COM technology. So capability is a CLSID - ID of client COM object that handle specific client ability (RTF-messages, buddy icons, chat, crypting, games). Here is the list of known CLSIDs: <img src="pictures/aim.gif" width=16 height=16 alt="Used in ICQ"> {09461341-4C7F-11D1-8222-444553540000}  Client supports voice chat.

Currently used only by ICQ clients. ICQ clients and clones use this GUID as message format sign. Trillian client use another GUID in channel 2 messages to implement its own message format (trillian doesn't use TLV(x2711) in SecureIM channel 2 messages!). <img src="pictures/aim.gif" width=16 height=16 alt="Used in AIM"> {0946134A-4C7F-11D1-8222-444553540000}  Client supports games.

The previous appears to be correct, but in some versions of winaim, this one is set. Either they forgot to fix endianness, or they made a typo. It really doesn't matter which because the meaning of them is the same. <img src="pictures/aim.gif" width=16 height=16 alt="Used in AIM"> {0946134B-4C7F-11D1-8222-444553540000}  Client supports buddy lists transfer.

It also lets ICQ users show up in buddy lists for AIM users, and AIM users show up in buddy lists for ICQ users. And ICQ privacy/invisibility acts like AIM privacy, in that if you add a user to your deny list, you will not be able to see them as online (previous you could still see them, but they couldn't see you. <img src="pictures/aim.gif" width=16 height=16 alt="Used in AIM"> {0946134E-4C7F-11D1-8222-444553540000}  Client supports UTF-8 messages.

From Aleksandr Shutko: Changes in new AIM clients

Changes discovered in new AIM clients by John Roark

I have been investigating the latest versions of AIM (5.2.3277) and found that capability CLSIDs are not passed with BUDDY__ARRIVED anymore... That is TLV(0x000D) still comes with SNAC(03,0B) but it only contains CLSIDs not of the form {0946xxxx-4C7F-11D1-8222-444553540000} like the chat CLSID {748F2420-6287-11D1-8222-444553540000}. instead SNAC(03,0B) contains a new TLV of type 0x0019 that contains a list of two byte CLSID diffs for example the following CLSIDs: 0946134A 4C7F 11D1 8222 444553540000 0946134B 4C7F 11D1 8222 444553540000 0946134D 4C7F 11D1 8222 444553540000 09461341 4C7F 11D1 8222 444553540000 09460000 4C7F 11D1 8222 444553540000 09461343 4C7F 11D1 8222 444553540000 094601FF 4C7F 11D1 8222 444553540000 09460001 4C7F 11D1 8222 444553540000 <-- new CLSID for encryption 09461345 4C7F 11D1 8222 444553540000 09461346 4C7F 11D1 8222 444553540000 09461347 4C7F 11D1 8222 444553540000 Is now represented as just: 134A 134B 134D 1341 0000 1343 01FF 0001 <-- encryption 1345 1346 1347   I can confirm this for ICQ (currently ICQ2003b & ICQLite4.1). This is not replacement for 0x0D tlv, but just the effective try to reduce traffic from ICQ servers. You can found TLV(0x0D) & TLV(0x19) in single packet.
