Greetings WebGL WG,|
The latest editor's draft of the File API now includes a reference to the Typed Arrays work; basically, the underlying Blob interface exposes an ArrayBuffer property. I believe this is the right way forward; web developers can make use of the view they wish to use.
-------- Original Message --------
Greetings WebApps WG, I have updated the editor's draft of the File API to reflect changes that have been in discussion. http://dev.w3.org/2006/webapi/FileAPI Notably: 1. Blobs now allow further binary data operations by exposing an ArrayBuffer property that represents the Blob. ArrayBuffers, and affiliated "Typed Array" views of data, are specified in a working draft as a part of the WebGL work . This work has been proposed to ECMA's TC-39 WG as well. We intend to implement some of this in the Firefox 4 timeframe, and have reason to believe other browsers will as well. I have thus cited the work as a normative reference . Eventually, we ought to consider further read operations given ArrayBuffers, but for now, I believe exposing Blobs in this way is sufficient. 2. url and type properties have been moved to to the underlying Blob interface. Notably, the property is now called 'url' and not 'urn.' Use cases for triggering 'save as' behavior with Content-Disposition have not been addressed, although I believe that with FileWriter and BlobBuilder they may be addressed differently. This change reflects lengthy discussion (e.g. start here) 3. The renaming of the property to 'url' also suggests that we should cease to consider an urn:uuid scheme. I solicited implementer feedback about URLs vs. URNs in general. There was a general preference to URLs, though this wasn't a strong preference. Moreover, Mozilla's implementation currently uses moz-filedata: . The current draft has an editor's note about the use of HTTP semantics, and origin issues in the context of shared workers. This is work in progress; I have removed the section specifying urn:uuid and hope to have an update with a section covering the filedata: scheme (with filedata:uuid as a suggestion). I welcome discussion about this. I'll point out that we are coining a new scheme, which we originally sought to avoid :-) 4. I have changed event order; loadend now fires after an error event . -- A*  https://cvs.khronos.org/svn/repos/registry/trunk/public/webgl/doc/spec/TypedArray-spec.html  http://firstname.lastname@example.org/msg06137.html  http://dev.w3.org/2009/dap/file-system/file-writer.html  http://lists.w3.org/Archives/Public/public-webapps/2010JanMar/0910.html  http://lists.w3.org/Archives/Public/public-webapps/2009OctDec/0462.html  http://lists.w3.org/Archives/Public/public-webapps/2010AprJun/0062.html
