Metacat

use logging, not system.out

consolidate session management and parameter preparation in the superclass

throw exceptions up the call stack rather than catching and handling them differently for each possible rest path

consolidate multi part handling in the super class - subclasses need only call the appropriate helper to get access to the needed resources. superclass does some validation to make sure the files are in place in the request

cleaning up the handlers -- removing superclass methods.

refactor to use D1RestServlet and D1ResourceHandler for the D1 rest interface

deprecate the old rest servlet in favor of the new D1-specific (CN/MN) versions

MN rest servlet, handler and mappings

share getSystemMetadata (before refactoring the superclass)

share getSystemMetadata (before refactoring this superclass)

Add placeholder NotImplemented exceptions for getOperationsStatistics() and getCapabilities() in MNodeService.

Implement MNCore.ping() by testing for a successful database connection.

Minor housekeeping - tabs to spaces.

Implement update() in MNodeService. Handle both XML science metadata updates and data object updates. Keep system metadata up to date, and log the update event.

Make isScienceMetadata() protected for access from subclasses.

Add insertSystemMetadata() to D1NodeService, wrap the exception handling from calls to IdentifierManager.

Add updateSystemMetadata() to D1NodeService as a helper method to wrap the exception handling from calls to IdentifierManager.

At Ben's suggestion, add metacatUrl to D1NodeService and make it available to subclasses. Set the metacatUrl in the constructor using SystemUtil rather than all roll your own PropertyService calls. More concise. Also, log the delete event in MNodeService.delete().

add CNRestServlet and mappings for urls in the form:
/d1/cn/*
This extends existing code for CN-specific handling. MN handling will be analogous and is forthcoming

share the deserializer method with subclasses

throw NotAllowed in MNodeService.delete() when isAuthorized() returns false.

Implement the MNStorage.delete() MNodeService. There is debate about what permissions are needed to 'delete' an object (archive it in metacat terms): D1 'WRITE' (metacat 'write') or D1 CHANGE_PERMISSION (metacat 'all'). For now we are using CHANGE_PERMISSION until it is ironed out.

add shared operations for authorization

share tempDir method with subclasses

make RestServlet and ResourceHandler extendible for D1 CN and MN handlers

use session member variable now that we actually have it

isAuthorized: check for nulls in Session subjects, catch any unexpected errors and deny access when in doubt

remove CrudService calls in favor of MNodeService

Remove setParamsFromRequest() from D1NodeService. This was called (previously as CrudService) from ResourceHandler, but will be deprecated in favor of manually creating a param map for each method that needs to pass params on to MetacatHandler.

Implement [MN|CN]Storage.create() in D1NodeService. Since MetacatHandler requires an IP for event logging, we pass in the metacat URL (hold over from CrudService). To do this in the abstract D1NodeService, change the constructors to take metacatUrl as a parameter and get the URL from the metacat properties file in getInstance() of the subclasses. Needs testing.

include URL in resolve() method as well as placeholder for preference

Metacat does not implement CNRegister

Implement CNRead.synchronizationFailed() in MNodeService. Note: The CN URL is not yet available in the SynchronizationFailed exception, but will be once the d1_common_java exception is updated. See https://redmine.dataone.org/issues/1656. Once updated, change this method to explicitly state the CN URL making the call.

Change Metacathandler.read() to be public since it's internal to Metacat, and use read() in D1NodeService after isAuthorized() for the calling Subject from the Session object.

Implement MNRead.listObjects() in MNodeService.

Implement MNRead.describe() in MNodeService.

Implement MNRead.getChecksum() in MNodeService.

Minor formatting changes - tabs to spaces, indents, etc.

Implement [MN|CN]Read.get() in D1NodeService. Added setParamsFromRequest() to pass through parameters from the request object. Since the D1 Authorization API doesn't specify which authentication system a subject belongs to, we don't know if the subject listed is a KNB LDAP DN. isAuthorized() may return true for a mapped identity, but we don't know the DN of the KNB identity per se. This needs to be tested.

-use every Subject in the session (alt Ids and Group membership)
-consolidate to single isAuthorized method

throw exception for unimplemented methods

implement resolve() method

implement assertRelation

implement CNReplication.setReplicationStatus() but with a note about selecting which replica's status should be set (right now it is all)

implement CNReplication.setReplicationPolicy

correction: implementation is CN-specific

implement getChecksum() in the superclass

implement getChecksum (retrieves from system metadata)

use shared get() method from superclass

use shared getLogRecords method

Remove isAuthorized(), setAccessPolicy(), and getLogRecords() methods since they're implemented in the superclass.

use Permission, not Event for isAuthorized() methods

do not delete the access rules when we "archive" the document on "delete" (commented out for now)

allow reading from xml_revision table when we are the doc owner

CNCoreImpl is replaced by CNodeService

implement CNAuthorization

Metacat does not implement CNIdentity - it is a stand-alone service

implement registerSystemMetadata

implement object format methods - using a separate class to do the actual metacat lookup/caching so that teh CN implementation looks cleaner

implement getLogRecords

include latest D1 common/lib changes

Initial check in of the MNodeService stub methods that implement the D1 MN* interfaces. CrudService methods will be transitioned into this class. The methods follow the D1 0.6.2 API thus far.

Also changed CNodeService to reflect minor changes to the D1NodeService class.

Add a static getInstance() method to CNodeService and make CNodeService a singleton.

Initial check in of the CNodeService stub methods that implement the D1 CN* interfaces. CNCoreImpl methods will be transitioned into this class. The methods follow the D1 0.6.2 API thus far.

CNAuthorization.isAuthorized() and MNAuthorization.isAuthorized() differ. Removed it from the base class.

getChecksum() is intentionally different on the CN vs MN, so I'm removing it as a common method.

Initial check in of the D1NodeService class that provides methods common to both CNodeService and MNodeService implementation classes. The common API methods are:

Methods common to CNCore and MNCore APIs
getLogRecords()

Methods common to CNRead and MNRead APIs...

placeholder for setting up certificate manager

remove AuthToken (use session). Remove login() call. Use AccessPolicu object to set public read permission

take getLogRecords impl form CrudService and use in CNCoreImpl

escape quotes when processing returnfield with predicates. example:
<returnfield>dataset/dataTable/physical/distribution/online/url[@function='download']</returnfield>

Updated MetacatPopulator to now use ObjectFormatCache.getInstance(). Note: problems remain with the authentication API changes - calls to mn.login(), etc. need to be addressed.

Removed ObjectFormatService in favor of CNCoreImpl

Added support in ResourceHandler for the /formats collection. Added listFormats() and getFormat() method, both of which call CNCoreImpl methods to handle the call.

Updated CNCoreImpl to implement listFormats() and getFormat(), and changed calls to ObjectFormatCache in IdentifierManager, MetacatHandler to call getInstance(). Removed the ObjectFormatService registration from MetaCatServlet since it is replaced by CNCoreImpl.

add option for replicating system metadata (dataone)
https://redmine.dataone.org/issues/1626

use Data Manager Library to parse EML when needed in DataONE classes.
(augmented DML to parse data format elements in EML to estimate MIME type)
https://redmine.dataone.org/issues/1634

When calling SystemMetadata.getObjectFormat(), return the string value of the ObjectFormatIdentifier rather than ObjectFormat.toString() (which no longer returns the fmtid string).

When calling SystemMetadata.getObjectFormat(), return the value of the ObjectFormatIdentifier rather than ObjectFormat.toString() (which no longer returns the fmtid string).

organize imports so that it is clearer what dependencies exist on the D1 jars

include create() and reserveIdentifier() methods

include override annotation for register method

use Date not joda's DateTime

expose spatial cache regeneration option in the admin interface

force replication for newly-registered system metadata

Merged in the D1_0_6_2_BRANCH changes that include the transition from ObjectFormat calls to ObjectFormatCache calls.

check system metadata for the id as well (in cases when we only have system metadata)

include GUID column for xml_access and related methods for storing/retrieving access rules

implement the old interface for now (until 0.6.2)

include CNCore implementation - only registerSystemMetadata is implemented at the moment. also - updated d1 jar (0.6.2) should be used since that is where the method is defined.
would like to consider making ResourceHandler more modular - seems like it does A LOT of different things

include System Metadata forced replication - just need to figure out when to call it!

handle timed replication of system metadata. there are still a few outstanding issues:
-track server location of system metadata-only entries
-replication policy flag for system metadata-only entries?
-locking for replicated entries?
-forced replication of entries

read and write D1 access policy rules from metacat xml_access table.
still TBD: which mechanism takes precedence when there are systemMetadata access rules and EML access rules and other access rules?

persist system metadata replication policy and status using db tables

rework SystemMetadata creation when inserting documents via the Metacat servlet api (in which case there was no client-supplued system metadata)

do not look in systemMetadata for a docid->guid mapping

transfer full System Metadata (as XML) during document and data replication

-remove system metadata guid -> local id mapping (there is no document for system metadata now)
-include system metadata elements when replicating data objects (TODO: transfer all system metadata structures with the docinfo request).
TODO: remove docid+rev from the systemMetadata table definition

do not use XML files for storing SystemMetadata - use DB tables only.

Modified Metacat to build against the D1_SCHEMA_0_6_1 branch of the dataone schemas by incorporating the 0.6.1-SNAPSHOT version of d1_common and d1_libclient libraries, and refactoring Metacat code references to the d1 schema changed types.
