Note that, because attachment tiddlers use ***TW-native section syntax***, you can easily edit it as needed by employing the standard TW editor, without needing any custom fields at all. It also makes it easy to embed the content of individual sections into other tiddlers by using TW standard <<tiddler TiddlerName##sectionname>> syntax.
While this is good for TiddlyWiki, especially those which are file:/// based, it is less good for server-side storage systems that store individual tiddlers (rather than whole wikis). TiddlyWeb being the example that I know about. In TiddlyWeb a tiddler is stored a combination of headers (attributes and fields) and a body. That body is usually wikitext, but if the 'type' attribute is set, you can put pretty much anything in the body. How it is stored depends on the storage system, the default text store encodes MIME types that start with something other that 'text/' in base64 encoded form. When such a tiddler is retrieved from the server it is packaged up according to its mime-type and the mime-type of the Accept header provided in the HTTP request. If you ask for JSON you get a JSON dictionary with the text attribute as the base64 encoded binary content. This can then be injected into a TiddlyWiki as required. What I would prefer to see for binary tiddlers is: * tiddler.text is either a data uri containing encoded binary stuff or remote URI which has the stuff * tiddler.fields[something] contains metadata about the binary stuff including amongst other thing an indicator that this is a binary tiddler * Core or CoreTweaked support for binary tiddler awareness in TiddlyWiki, such that refresh or edit of a binary tiddler enters a binary tiddler code path. -=-=- The above is not necessary, though, if a structured binary tiddler with sections is preferred. For TiddlyWeb, if the format is specced out, we could include support for it in the tiddlywiki serializaiton in TiddlyWebWiki. -- Chris Dent http://burningchrome.com/~cdent/ [...] -- You received this message because you are subscribed to the Google Groups "TiddlyWikiDev" group.
