Data Access API QA Review
-------------------------
Key: GEOT-1063
URL: http://jira.codehaus.org/browse/GEOT-1063
Project: GeoTools
Issue Type: Improvement
Components: admin
Affects Versions: 2.4.0
Reporter: Jody Garnett
Assigned To: James Macgill
Priority: Blocker
The DataAccess api was born out of the following *needs*:
- limitations of String as a representation of TypeName in DataStore API
- poor intergation with metadata (ie need GeoResourceInfo at a minimum)
The first targets for the concept are:
- Replace Grid Coverage Exchange
- POJO Domain model (thanks to JPOX-Spatial unsupported module)
The StreamingRenderer has been updated to make use of the DataAccess api (ie
Source); we have not reproduced all the hacks that protected StreamingRenderer
from incorrect FeatureSource metadata (ie wrong coordinate reference system
etc...) on the grounds that we do not have to accept mistakes from
implementations (we should submit bugs, decent error messagesn and offer
wrappers to end users so they can fix problems).
This issue has been marked as a blocker on the 2.4 release:
- as we cannot afford to confuse these interfaces
- we need to ensure FeatureSource can cleanly extends Source with no method
conflict
- ensure the interface is a good compromise for Feature, Pojo, GridCoverage use
- seperate out readonly from readwrite
