Found at: www.ITSware.net/ITSschemas/ Last Update Oct 11th 2006
The
schema sets found in this file area represent both draft and final adopted
releases of standards efforts from the primary ITS standards organizations, as
well as schema sets devised by local deployments for their own needs. You are
free to browse this directory and use what you find.
Refer
to the actual standards documents (printed or on-line) from the issuing
Standards Developing Organization (SDO) for details of proper use regarding
these data concepts. Ask questions of
the committee or SDO responsible for that schema in their area of the standards
support forum ( www.ITSstds./org ) The standards generally explain how these
data concepts are to be properly used and contains much more information than
the schema itself. Many standards also
now have a Users Guide which provides
further details and often well formed XML fragment for your review. Some standards are free, others are
available at a low cost, consult the SDO for specific details.
The
naming and revision system used in ITS schema is briefly outlined in this document for
those that have not seen this system in use.
In brief, the releases are organized by Functional Area or FADDs
(Functional Area Data Dictionary).
Within each FADD is a folder with a specific unique release number. Within that folder is one complete set of
schema files. Typically a primary
schema file and the associated partial schema files that it used from
elsewhere.
In
order to actually locally use the schema sets found here you must understand
how the standard you wish to use is related to any other standards which it may
depend on and include. This is most
clearly seen in the revision and file naming system used to differentiate each
version of the schema and the other schema files which it in turn uses. You will likely have to pick a set of schema from one of the SDOs then remove (or add) those
portions of messages and data concepts
which you do not need in your deployment.
This process, called local
profiling, will result in the specific schema you need for your
deployment. This becomes a critical
part of your deployment and software procurement process and you will likely
use it in the contractual bidding with your vendors. When you have created this document set (several files in fact),
please up-load it here so that others may benefit from you work. If you are using the Mini-Edit tool to
create your local schemas system, this is largely automated for you.
How
to use these schema files in a typical procurement specification that wished to
be “consistent with the US ITS standards”
- text to be provided.
How
to judge locally developed schema files to determine if they are “consistent
with the US ITS standards” - text to be provided.
Note that you can browse this
file system, viewing the directories at each level, as you see fit. You are encouraged to copy entire directories to your own servers
as the need arises. The path naming
follow the recommendation outlined above.
More recent efforts typically have additional supporting information
besides the schema files (html documentation being common). The level of the information provided is up
to the schema creator.
Note for Mini-Edit Users The database used to created a given schema set may also be found
in the same folder with some releases.
This can be downloaded and used in the Mini-Edit tool to create further
derivative works as needed. See the section of the standards forum on Mini-Edit
use for how to obtain and install this free tool.
Note for Schema submitters: Send your schema file set in a zip file which meets the naming
rules outlined here to MEdit_Support@ITSware.net
and it will be uploaded into the prosper folder for use.
