Brian Foster commented on OODT-72:
----------------------------------
Here is an alternative to having to set FileLocation at ingest time:
- modify getMetadata(Product) and getReducedMetadata(Product, List<String>)
such that if System property 'org.apache.oodt.cas.filemgr.complete.metadata'
equals true (open to suggestions on that property name) Product/Reference
values will be added to the Metadata
- here is the mapping of Product to Metadata fields:
product.getProductId() -> ProductId
product.getProductName() -> ProductName
product.getProductStructure() -> ProductStructure
product.getTransferStatus() -> ProductTransferStatus
product.getRootRef() -> ProductRootReference
- For the References returned by product.getProductReferences() the following
Metadata fields will be added (order will be maintained, such that data store
ref at index 0 will map to orig ref at index 0, etc . . .):
ProductDataStoreReferences (list of all data store references)
ProductOrigReferences (list of all orig references)
ProductMimeType (list of all references' mime-types)
ProductFileSize (list of all references' file sizes)
- Nominally this patch will add all described Metadata fields above if System
property (mentioned above) is set to true . . . if later it is determined that
only a subset of these fields are typically desired, then maybe an additional
System property could be added to filter the list to a subset (or reduced set)
of fields that should be added

> Key: OODT-72
> URL: https://issues.apache.org/jira/browse/OODT-72
> Project: OODT
> Issue Type: Improvement
> Components: file manager
> Affects Versions: 0.1-incubating
> Environment: none
> Reporter: Brian Foster
> Assignee: Brian Foster
> Priority: Minor
> Fix For: 0.2
>
>
> Ingest order:
> - add product to catalog
> - metextractors run
> - add metadata to catalog
> - versioner runs (on client or on server)
> - add references to catalog
> This prevents Metadata elements such as FileLocation from being set based off
> Product References since metadata is added to catalog pre-versioning
> - A known work-around is to run the versioner twice (once in a MetExtractor
> and again when the Versioner is run in the ingest process) . . . however this
> is very much a work-around and setting elements such as FileLocation is a
> very common functionality.
> I purpose that Versioning take place before MetExtractors run.
