Include option in EMLDatasource actor to use 'most recent' data
Added by ben leinfelder over 16 years ago.
Updated about 16 years ago.
Description
Change EMLDatasource actor to allow user to specify 'most recent version' of package data be used.
On workflow open?/execution?, actor will check the [remote] source for latest version of the data, fetch it and use that for the run.
Will need to be careful of schema/structure changes to the data tables.
Added check to EML200Datasource actor.
Uses RepositoryManager to make webservice call to earthgrid.
Still need to refactor the services to use the object manager method of managing eco/earthgrid services. essentially need to have the search and selectable stuff in the classes that extend Repository.
with the changes to how ecogrid can be searched using authentication credentials, i've also changed how the eml actor checks for the latest version.
Services can now be related to each other by sharing the same "clusterName" - given a queryservice, we can find the appropriate identifierservice to use for looking up the latest version of the metadata/data.
this change has been included in RC1
