Re: Re: Album hierarchie

Hi All,


A few thoughts....
Heirarchical classification for weblogs has been done very well by 
blojsom [www.blojsom.org] - where categories and subcategories of blog 
posts are identified in the same way as unix paths -

/technology/computing/macosx or /comedy/usa/cheers for instance.

This is a very intuitive system as it allows categeories to be accessed 
through the site URI - eg:

www.timcowlishaw.co.uk/blojsom/blog/design/typography/tschichold/ -very 
intuitive for the end user. Blojsom also uses text files and the 
filesystem to organise its data - although this is not relevant to 
pixory.

Perhaps pixory could employ a similar system?

as concerns access control, extending the filesystem analogy, when 
changing permissions for a directory in *NIX, you can choose whether to 
alter all children as well using the -r switch to chmod. surely all the 
pixory admin console needs is a "change access recursvely" check box to 
cope with album heirarchies?

hope this is of some interest,

tim
