<p>XMPP is designed for sending relatively small fragments of XML between network entities (see &xmppcore;) and is not designed for sending binary data. However, sometimes it is desirable to send binary data to another entity that one has discovered on the XMPP network (e.g., to send a file). Therefore it is widely recognized within the Jabber community that it would be valuable to have a generic protocol for streaming binary data between any two entities on the network. The main application for such a bytestreaming technology would be file transfer, for which there are currently a number of incompatible protocols (resulting in a lack of interoperability). However, other applications are possible, which is why it is important to develop a generic protocol rather than one that is specialized for a particular application such as file transfer.

Usage of jabber/xmpp for stock data transmission would be a nice-to-have. This jep defines transmission of stock ticker values via XMPP based on publish/subscribe. A component, client or alike may publish stock data in this specified way, after creating a node. However, first of all a node on the pub/sub server must be created, this jep recommends creation of the node in the domain 'stocks/', with specific stock value published in the ticker name domain space, i.e. 'stocks/CATG.DE' or 'stocks/602345'. This jep uses the domain 'stocks/' for example data. Usage of jabber/xmpp for stock data transmission would be a nice-to-have.

So, what this JEP comes down to: it defines the data architecture for stock data and it specifies, that a 'stocks/' node is recommended to exist, which again holds all symbols as subnodes, which again hold either '/realtime', '/bar' or '/news' as subnodes. The 'bar' subnode contains a 'time descriptor' subnode. The sort of the symbols is defined through the service provider, who can i.e. support Y!ahoo finance symbols, (german) WKNs or official stock symbols.

<p>Within Jabber, namespaces are used to scope data that conforms to a schema (often data that extends the core protocol in some fashion). In addition, namespaces can also provide context for the field variable names used in jabber:x:data forms and reports. This proposal makes that link explicit by defining a mechanism for linking a namespace name with a form and the field names and types used in that form. Specifically, the namespace name is specified in the form as the value of a hidden variable called "FORM_TYPE".</p> <p>Within Jabber, namespaces are used to scope data that conforms to a schema (often data that extends the core protocol in some fashion).
