Change Log

2013-10-17: Version 1.2. Minor edits

• Added language indicating restricted access to log information by public user
• New version of plantuml.jar

2012-10-09: Version 1.1. Clarifying count parameter for slicing.

• No functional changes were introduced.
• listObjects, listSubjects, getLogRecords descriptions were updated

2012-09-28: Version 1.1. Adding MNQuery API

• Added MNQuery API as an optional Tier 1 API with the same method signatures as the CNRead.Query* method definitions.

2012-09-25: Version 1.1. Revising proposed Query API

• Updated proposed search API following review and discussion. Including draft changes to 1.1 dataoneTypes.xsd
• Changed search2 to query
• Changed listSearchFields to getQueryEngineDescription
• Changed listSearchEngines to listQueryEngines
• 2012-09-06: Version 1.0. Removed ambiguous exception serialization info

2012-08-20: Version 1.1. Augmenting Search API

DRAFT edits for review:

• Added method search2 which enables return of arbitrary structure as determined by the selected search engine.
• Added method listSearchFields which returns a list of fields that can be searched using a specified search engine.
• Added method listSearchEngines which returns a list of search engines available.

2012-05-31: Version 1.0, Correction to URIs in Resource Maps

• Corrected URI constructs in the resource map data package documents to use resolve rather than getObject URIs so that clients can take advantage of the ObjectLocationList or HTTP status 302 redirect.

2012-05-02: Version 1.0, MethodCrossReference.xls

• Moved MN systemMetadataChanged from MNStorage API to MNAuthorization API so that the method appears in Tier 2 operations.

2012-05-01: Version 1.0, MethodCrossReference.xls

• The MN method getReplica was incorrectly located in Tier 4, effectively preventing any MN implementation except Tier 4 nodes from acting as replication sources. This has been corrected, with the method moved to the MNRead Tier1 API. The method description was updated accordingly.
• Existing MNStorage.delete renamed to MNStorage.archive, better reflecting its action.
• New MNStorage.delete operation added for Tier3. This operation does actually delete the content from the node, removing it from DataONE services (the node may choose to also delete the bytes)
• New CNCore.archive operation performs the same action as MN.archive, except the operation triggers a change notification to all nodes containing the object.
• New CNCore.delete operation intended to be used only by administrators when there is a requirement to remove an object from the entire DataONE system. Memory of the identifier persists, preventing its reuse.

2012-03-26: Version 1.0, MethodCrossReference.xls

• Corrected typo in REST description for listObjects which had lowercase formatid, corrected to formatId.
• Corrected order of parameters for getLogRecords, moving start and count to the end to be consistent with other method signatures.

2012-03-26: Version 1.0, MethodCrossReference.xls

• MNCore.getLogRecords() updated ‘pid’ parameter to string and renamed to ‘pidFilter’
• CNCore.getLogRecords() updated ‘pid’ parameter to string and renamed to ‘pidFilter’

2012-03-25: Version 1.0, MethodCrossReference.xls

• MNCore.getLogRecords() added an optional parameter pid that specifies the prefix of the pid for matching on log records. Support for this parameter is optional, and a MN implementation may silently ignore if present in the request and the node is unable to support the pid prefix filter.
• CNCore.getLogRecords() added an optional parameter pid that specifies the prefix of the pid for matching on log records. Support for this parameter is currently optional for CNs, and may be ignored if present in the request.
• MNStorage.GenerateIdentifier() new method added to the MNStorage API. This signature mirrors the CNCore.GenerateIdentifier method and is made available on Member Nodes as they may choose to have an organizational association with an identifier service.

2012-02-27: Version 1.0, MethodCrossReference.xls

• CNRead.search() clarified how to specify path and query separators in the value of parameter ‘query.’ Change xmit type of parameter ‘query’ to ‘path’, since it contains both path and query (to simplify client conformity testing)

2012-02-24 : dataoneTypes.xsd

• Correction to the contrabEntry definition
• Several documentation only changes

2012-02-17 : Version 1.0, MethodCrossReference.xls

2012-02-15 : Version 1.0, MethodCrossReference.xls

• CNCore.hasReservation() REST URL changed a POST message to GET /reserve/{pid}?subject={subject}

• Response type for CNIdentity.getSubjectInfo() and CNIdentity.listSubjects() changed from Types.SubjectList to Types.SubjectInfo
• Response for MNReplication.getReplica() corrected in the documentation to indicate response is an octetStream of bytes that represent the requested object.

  • pid removed from URL, it should be a param in the message body.
• Signature of CNCore.create()
  • pid removed from URL, it should be a param in the message body.

• Request method and endpoint for CNCore.hasReservation() was changed to POST and /hasReservation respectively.

2012-01-12 : Version 1.0, MethodCrossReference.xls

• Updated CNRead.resolve() to return a HTTP 303 See Other response on success
• Added CNCore.setObsoletedBy() to update the obsoletedBy information for an object. Note that the proposed endpoint may change pending discussion.

dataoneTypes.xsd

• https://redmine.dataone.org/projects/d1/repository/revisions/5754
• Deprecated MNAuthorization.setAccessPolicy. This is replaced by MNStorage.systemMetadataChanged

This is a Tier 2 method. It is accessed on the /dirtySystemMetadata REST endpoint.

2011-11-01 Version 1.0.0 Branch

2011-10-26 Version 1.0.0 Branch

dataoneTypes.xsd

The following changes were enacted on the dataoneTypes.xsd schema as a result of discussions during the DataONE all-hands meeting held during the week of October 18, 2011.

No further significant changes to dataonetypes.xsd are expected for version 1.0.0 of the DataONE infrastructure.

• unsigned long “serialversion” element added to the Types.SystemMetadata complex type. The serialVersion value is incremented upon any updates to a system metadata instance, and is used to indicate which is the current version (highest serialVersion is always the latest) of system metadata for an object.
• “fmtid” change to “formatId” in Types.SystemMetadata complex type
• “fmtid” change to “formatId” in Types.ObjectFormat complex type
• “fmtid” change to “formatId” in Types.ObjectInfo complex type
• email minOccurs change from 1 to 0 in Types.Person complex type
• boolean “verified” property added to Types.Person complex type. This value is true if the name and email address of the Person have been verified to ensure that the givenName and familyName represent the real person’s legal name, and that the email address is correct for that person and is in the control of the indicated individual. Verification occurs through a established procedure within DataONE as part of the Identity Management system.
