| + | #REDIRECT [[downloads-brainstorming]] |
| − | The purpose of this page is to capture software updates practices in the wild, as one effort to codify practices currently used in the automatic update system called Sparkle.

| − | == Context ==
| |
| − | | |
| − | Sites like [http://iusethis.com iusethis.com], [http://versiontracker.com versiontracker.com], [http://macupdate.com macupdate.com] and [http://download.com download.com] among others should be investigated and documented for object names and attributes.

| − | Among common data in a software update changelog are changes or fixes, completed bugs, new features or modified behavior, and known issues. A version number is also typically supplied, but takes on many forms and is not always numeric.
| |
| − | | |
| − | Lastly, this work should be seen as compatible with hAtom, possibly as a prelude to a format that could be embedded as the payload of an hfeed object.
| |
| − | | |
| − | Work should be carried out on the [[appcast-examples | Appcast Examples]] page.

| − | * [[downloads-brainstorming]] seems to have a similar goal. Could these two pages be merged? [[User:DenisDefreyne|DenisDefreyne]] 02:56, 28 Jul 2007 (PDT)
| |
| − | * [[hash-examples]] has a section about hAtom integration. The example uses a "download" class, which contains a rel-enclosure link as well as a span with "md5" and "checksum" classes.

| − | == Sparkle-specific Appcast enhancements ==
| |
| − | | |
| − | Sparkle adds a few extra features to appcasts:
| |
| − | | |
| − | * External release notes URL: used when the release notes are not included in the appcast itself
| |
| − | * MD5 sums and DSA signatures: used for some extra security
| |
| − | * Advanced version string: Sparkle determines the application version from the enclosure name, which is assumed to be APPNAME_VERSION.zip; the advanced version string allows this convention to be overridden
| |
| − | | |
| − | hAppcasts should probably support these features as well.
| |
| − | | |
| − | The MD5 sum and DSA signature is specific for an enclosure. It is, however, not possible to add these extra attributes to a [[rel-enclosure]] link; a larger "enclosure" microformat may be necessary (also see [[hash-examples]]).
