Hei Matti!

Can someone explain me the relationship with RDF's Object(literal) and
zz cell's enfilade?
I'll try.
In zz/xu all was clear since you did implement the structure and cells
actually didn't have anything like literals. Cell's container was actually
a pointer to an enfilade. Data was in mediaserver until now when data is
in literal and in storm? Confusing.
Ok, first of all: Everything will be in real RDF, i.e. triples of
URIrefs, anonymous nodes, and literals. Xu storage will be built *on top
of that*.
So we can have a literal with the following content (I'm making the XML
tags up here):
<alph:text uri="storm:block:482sanl3w24trg2" start="4" end="112"/>
<alph:text uri="storm:block:21354sfdaay3244" start="43" end="148"/>
This is the string the literal contains.
Alph ('xustorm') will interpret this as an enfilade. It will read the
Storm blocks referenced and take the Xanalogical data from there.
On the other hand, we will also be able to deal with literals like the
following:
2003-03-03T12:14:30Z
This represents a date in non-Xanalogical format.
We may show the date to a user as "3.3.03"-- and similarly, we may show
the enfilade to a user as the text it contains.
Clearer now?
