  • Is iPhoto's storage format known? I read somewhere that starting with Keynote (and following up on the preferences and stuff), Apple was to use XML as the storage format for an increasing number of its apps. Not to over-pitch XML (especially as Keynote's format could be much improved upon, notably by using SVG instead of copying it) but it would make export trivial, could be used directly in AxKit's image gallery, would allow one to search for pics using Find::File::Rule::XPath, etc.

      I don't condone what Apple did, but I don't condemn them either. Even Tim Bray has said on occasion that it is more important to start using XML than to wait for a nice-sounding whiz-bang specification to gel.

      I was in a position when I needed an Schema language for XML in 1999. Shortly thereafter, we needed an XML Query language for the same project, just before the first XM

      • Oh I know that ad hoc is good, I'm a great advocate of using ad hoc vocabularies and do so whenever there is no existing solution that satisfies me (which is why I never use DocBook, only convert to it).

        However SVG 1.0 has been around for a while, and Apple was on the WG. I know they wanted to use it for some OS X stuff but had to ship earlier than the spec was released. However I am having some trouble understanding why they're using things like <g transformation='1 0 2 2 3 6'> instead of <g transform='matrix(1 0 2 2 3 6)'> when that syntax has been around a long time and they took part in shaping it. Looking at the vocabulary closely, it really seems to me that they in fact were using quasi-SVG and went to some pains to change the names :)

        Also, Keynote might have been around for a while, but it's been industrialised now. Changing an XML format is trivial in any well built app (a simple reader, a simple writer), and I do expect support for a spec from companies that helped write it :)
