ALL entities

ALIAS
alias IDREF
ID
Hierarchial labelling base/blockid/.....
Check XML Schema and Namespaces
differentiate naming and physical hierarchy

OBJECTINSTANTIATION
Different object views

ALL are containers

selection defined as list of ID's selects a symbolic link inheriting 
some but not all
can copy so preserve after original edited
can override if want to change one ID

Container contents can be ordered or unordered
Not all subcontainers need be in order
e.g. objectives is not ordered wrt content in a course container
     However inside objectives container, there maybe ordering
of subobjectives

	order =ID1,ID2, ..
	      = Lexical
	      = As entered
	      = unordered

Handler = Manager, Renderer, Backend, client, or any servername/type

OBJECTVIEW if handler=renderer
	This view can require Manager to interpret specification
	DISPLAY TYPE = PC,Palm CAVE, thumbnail, default (multi-valued), Virtual Classroom
Here is where layout comes

Base Objects One reesource
Composite Objects Nontrivial container
Symbolic Objects defined by Alias

All Objects should have a
OBJECTRENDERING with handler=renderer
and internal OBJECTVIEW

All objects have a type
such as COURSECOMPONENT MULTIMEDIA IMAGE OBJECTIVE EVENT...
Stature=independent,edditable

If you copy a component, then that act becomes an event

We have two ways contents of a container can be defined
Explicitly in FISHXML
Implicitly where there one or more XML files defined in container
and these XML files reference FISHOBJECTS
These FISHOBJECTS will be parsed by Manager and symbolic links replaced etc

So need flavor=fish tag in such embedded attributes
Containers wich are XML files should have a tag
to say INTERPRET and where to interpret

Note we need to distinguish various actions
Interpretation of symbolic links can only be done by a fishmanager

If I selected a subset of objects in a container
eg image but not voiceover; could do by explicitly referencing

Suppose I define a container Foil1
It has
Symbolic link to anotherfoil1
delete anotherfoil1/audioover
add newaudioover
add anotherteacherannotation
replace button1 with newbutton1

Renderer casn edit object asdding overlaty etc
this becomes an event and a new edit subobject

Note in edit case, key is that take groupo of compoonents
and integrate

XML should define make and access as asccess can edit

Criotical issuie is unit for transfer from one server to another
Must generate table of contents
