==== Biology XML format ====

Experimental - possible future format for scalability. This XML could be submitted/edited directly by content contributors and automagically parsed into HTML. Note that every article has its own unique ID, and that each child tag within an article has a "lang" attribute to enable people to put in translations. The unique ID being wiki-editable is potentially dangerous - easy to change book IDs, duplicate ID numbers, etc. which is probably an argument in favor for a CMS (much as I hate to say it); this format would be easily transferable to a CMS.

Right now I'm just parsing the title, author, publisher date, and note tags, but more can be added if needed. There needs to be an instance of each tag with the lang attribute set to "default" (for when no language is specified, or a nonexistent translation is requested). Tags with no lang attribute are taken to be set as "default." The last valid version of each tag/lang combination is what is actually parsed. For instance:

<pre>
<title> A title! </title>
<author lang="en">Author1</author>
<author lang="en">Overwrite Author1</author>
</pre>

is the same as

<pre>
<title lang="default"> A title! </title>
<author lang="en">Overwrite Author1</author>
</pre>

Actual sample xml follows. [[User:Mchua|Mchua]] 11:03, 29 March 2007 (EDT)

<note language="en">A note in English</note>
<note language="es">A note in Espanol</note>
<note language="pt">A note in Portuguese<note>

<article id="2">

<note language="pt">Cores outonales, Parque nacional Wrangell-St. Elias, Alaska, EUA<note>
</article>
</pre>

The advantage to XML is that we can use DTDs to make sure the input format is nice and correct.

Doctype for OLPC biology library format - intended to be template for future article formats as well.
mchua 3/29/07 - created

The below notes are largely for content contributors who haven't seen DTDs before:
* a library consists of articles with unique IDs
* articles without assigned ID#s get an ID of 0
* title and author are required
* Tags can be marked with language attributes so you can specify what language you're writing in.
check to make sure the value for language you're putting in is valid, or the parser
won't recognize it!
* if no language attribute is specified for child tags, they get a value of "default"
(and will show up when users don't specify a language they want to view in,
or if the language they request does not have a translation yet.)

<!DOCTYPE BIOLOGY [

==== Alternative XML markup ====

Grouped by language - possibly easier for content contributors & translators, but (I perceive it to be) less flexible in terms of adding tags, languages, etc. on the parse-to-xhtml end. [[User:Mchua|Mchua]] 11:22, 29 March 2007 (EDT)

<pre>
<article id="1">
<default>
