Any time..!
Any where..!
Any data..!
Why Metacontent?
Users separate from Information!

time - viewing historical data at some point in the
future
space - physically separated or having limited
proximal access to the data and data collectors
subject area - not being a specialist in the
information domain that the data represents
A Hierarchical view of
meta-content Needs

Metadata

Database
Metacontent are facts that describes both
database organization and the data's fitness for
use.

The Concept of Session
HydraSpace
“Linking People and Information”
A session is a set of activities carried out
over a period of time and covering a
specified geographic area, which will
produce a new or updated spatial dataset.
A session layer is a common mechanism by
which users perform activities to acquire,
integrate and make use of spatial data.


Allows users to deal with a user task interface instead of
computer programs at the command line
Example: Commands required to be run to extract data for
validation:
execute cwodi.dropwindow('check3');
execute cwodi.createwindow('check3','halifax',-65.597,42.665,-63.59,44.67);
cwco userid=pierre/xxxx table=halifax window_name=check3 mdffile=check3co.mdf
rangecols=pro_depth
hhsort.exe hhsort.con check3sort.mdf check3co.mdf


Users only need to specify the user task they want to do
and the parameters for this task
Tasks can be re-configured at any point to take advantage
of upgrades, without the user needing to know new syntax
Task manager generates metacontent

Their challenges:





Distributed organization in four offices
More powerful data acquisition systems - large volumes
More types of products - adoption of IHO S-57 standard
New ENC update distribution method
Fewer staff - less budget

Define standard processes
Define user tasks executed by a series of automated
tools
Plan work sessions (projects)
Log user tasks as they are carried out
System-generated metacontent as automated user
tasks are executed
Monitor and control standard processes
