[mapguide-users] Fdo2Fdo

[Jason Birch]

FDO is open source.  If there are non-open parts of the specification,
I'd be EXTREMELY disappointed.  I'm not sure if using all caps was
enough to express the level to which I'd be disappointed...
 
It's frustrating that the default RDBMS providers require that you keep
the metadata in the database rather than mapping on the fly.  Given the
limited budget and the desire to integrate with the proprietary Autodesk
products, the PostGIS provider has been integrated with the core RDBMS
providers.  To me, it seemed more important to be able to use PostGIS
with Map 3D and spread the adoption of PostGIS by Autodesk users than it
was to enable access to existing PostGIS schemas.
 
It believe that what this means in the short term is that it may be
necessary to use Autodesk tools to populate it, and that you can not
just access existing data.  Longer-term, I'm sure that "foreign" schema
support will be added to this provider, but I think that this still
requires that you keep the metadata in the same data source (possibly in
a different schema?).  What I would really like to see is a third level
of function where all of the mappings are kept internally to FDO without
affecting the datasource.  I hope that over time FDO will give priority
to "on-the-fly" access to my data without making the data store
essentially proprietary to FDO.
 
I guess a lot of this is probably stemming from FDO starting out as a
way of storing Autodesk data in multiple sources, rather than as a
generic data access mechanism.  
 
If any of this is incorrect (Paul, Mateusz) I'd appreciate correction.
 
In the mean time, if you manage to extend fdo2fdo to support this
metadata, that would be a great interim measure.

Hm, I wasn't thinking in that direction, but Map is still needed if you
wan't to have full FDO Meatada arround your data.
 
This tool will create plain tables in Oracle (indexes, keys,..) and this
data can be used in MapGuide or Map as foreign schemas or using
King.Oracle Provider.
 
If you would like to have full FDO Metadata, MAP is still needed.
 
P.S.
Not sure , if for non Autodesk tool is correct ( i mean some licence
restrictions) to create FDO metada also ?
I suppose it should be, but would be nice if someone from Autodesk would
confirm that.
I was already doing that once for Oracle Topology, puting FDO metadata
arround it.

This is pretty cool Haris.
 
This means that users that aren't able to purchase a Map 3D license can
load data into RDBMS data sources.

Hi,
 
Fdo2Fdo is a tool I am using to work with, learn and test FDO and
perhaps it can help to someone else also.
It is a FDO client application for copying FDO Data Sources and manage
FDO Data Sources with additional tools to work with Oracle.
It has two parts: standard library as fdo client and windows
application.
 
Some features:
 
1. Copy to/from SHP, SDF, Oracle ( didn't tested others but could work)
http://www.sl-king.com/fdo2fdo/screenshots_copy.html
 
2. Copy to Oracle and it will setup all stuff so you can view it
immediately in MapGuide (sdo metadata, spatial index, layer type,
primary key)
 
3. Fdo Toolbox: useful utilities for testing fdo providers and schemas
http://www.sl-king.com/fdo2fdo/screenshots_fdo.html
 
4. Oracle toolbox - manage sdo metadata, spatial index, primary keys
http://www.sl-king.com/fdo2fdo/screenshots_ora.html
 
5. API c, .net  http://www.sl-king.com/fdo2fdo/fdo2fdo_api.html
 
 
You can get it here:  www.sl-king.com/fdo2fdo
 
 
It is a self contained application.
It is 38 MB .zip file which you unzip and ready to go. It contains:
complete fdo, shp,sdf,king.oracle provider, oracle instant client and
needed microsoft redistributables.
 
I tested it around sdf,shp and oracle but it is general fdo client so it
could work with others also, if not let me know and I will try to fix
it.
 
If some of this, is material for open source I am happy to make it so.
 
Haris
