Metacat

use update method to update the mapping between local and guid (d1) when we get a force replication request that is an "update

generateMissingSystemMetadata was swallowing Exceptions instead of throwing. Refactored so that specific exceptions are thrown, affecting [create/update]SystemMetadata methods, too.

committing changes related to the new restservice update specification (newPid vs. obsoletedGuid)

replace whitespace in generated docid scope (sanparks patch from 1.9.4 branch)

use outputstream as an object, not a string. relax the Map typing to allow for mixed values. (sanparks patch)

use "object_format" element consistently so that it is replicated across instances
https://redmine.dataone.org/issues/1514

remove very old "metacat webservice" code - as far as i can tell it is never referenced or used. plus we have eocgrid and the new D1 rest services covering this territory now

zero padded date string in DocumentUtil.generateDocumentId() for readability

Use SystemUtil.getContextURL() in ResourceHandler to construct the DataONE service URL (rather than direct calls to PropertyService). This handles http and https URLs, and strips the :80 or :443 for the well known ports.

Minor changes to MetacatHandler:
- Improved logging where MetaCatServlet.class was used in getLogger() rather than MetacatHandler.class (holdover from the refactor)
- Minor formatting changes, and replacement of 'MetaCatServlet' with 'MetacatHandler' in the logging output as needed.

improved multipart handling (improved logging messages, code, and error checking). Added exception classname to error output when the generic Exception is thrown. Added error check for cases of null value for file parts 'sysmeta' and 'object.'

added a few debugging lines in createSystemMetadata() related to contents of identifier strings

Modified IdentifierManager.getDocumentInfo() to include the docid in the returned hash map, since it is useful to be able to obtain the docid and rev separately from a given fullDocidWithRev (e.g. test.1.1).

fixing annoying error message inaccuracy

Changed AuthLDAP to deal with cases where getAttributes encounters non-string
attributes (which used to cause a ClassCastException). Now, if an attribute
value can not be cast to string, we catch the class cast exception and just
skip this value. This only typically occurs when an LDAP server is set to send...

MOdified MetacatHandler to catch cases where ObjectFormat is not being set properly on data files when
generating SystemMetadata. When the EML document contains a format for an entity that maps to a null
type in ObjectFormat.convert(), then the type ends up being null and an error is generated on insertion...

allow "docid override" queries to include the results of a "normal" query - if the operator is left null, it acts as the usual override, otherwise UNION and INTERSECT modes can be used to either augment or refine the results.
this is for incorporating semantic+spatial+keyword queries into one query operation/result

remove System.out statements in favor of logging

Removed hardcoded D1 node type in ResourceHandler and added in a new 'dataone.nodeType' property. Also added 'dataone.coordinatingNodeBaseURL' property which points to the CN that stores the authoritative object format list. If this instance of Metacat is a CN, it may point to itself.

ResourceHandler in Metacat was set to return the KNB site URL as the MN base URL rather than the node Id. Fixed. https://redmine.dataone.org/issues/1390

initialize the HandlerPluginManager

allow the addition of properties via code

add event notification for insert/update/delete on documents (for semtools plugin)

do not attempt to check permissions when reading documents for systemMetadata generation (unless I completely do not understand this feature - please verify!).

do each table separately with it's own connection - running into memory issues on dev.nceas running this.

do not drop nonexistent table (identifier is not in 1.9.3)

This is the start of the ObjectFormatService, which manages the list of object formats registered within Metacat. This includes schema types, mime types, and other information related to a particular format. The service provides functionality for the DataONE MemberNode and CoordinatingNode components, with CoordinatingNodes providing the authoritative list of object formats. See https://redmine.dataone.org/issues/1378....

Bug 3835 - design and implement OAI-PMH compliant harvest subsystem
Minor bug fix to handle irregular Metacat docids containing two or more dot ('.') characters. In the LTER Metacat, the following docids (scope and identifier, excluding the revision value) have that characteristic:...

Bug 3835 - design and implement OAI-PMH compliant harvest subsystem
Return a 'badVerb' response when the 'verb' request parameter is missing from the request. Previously this generated a NullPointerException.

use the jaxb date parser for ISO 8601 formats. the numeric and date node values are now calculated after the document has been successfully inserted in the db so any sql exceptions do not prevent the raw node data from being saved.
http://bugzilla.ecoinformatics.org/show_bug.cgi?id=2084

rollback the accessDAO changes - leaving well enough alone.

only include accessfileid when it is not toplevel

include accessfileid and subtreeid when inserting xml_access values

use access control dao for setting access in EML parser. send additional xml_access info in replication request

insert/update documents with null user and null group to circumvent access control restrictions then update the user_owner and user_updated values to reflect what exists on the originating server (pisco)

use 'user_updated' field when writing the replicated document - allows most recent ownership/permissions to be used (in case LDAP groups have shifted) and is more accurate for both updates and initial inserts (hopefully addresses the replication issue we are having with pisco)

add support for temporal element query in pathquery
http://bugzilla.ecoinformatics.org/show_bug.cgi?id=2084

DocumentImpl.delete() now throws finer grained exceptions (not a general exception). Consequently, the classes that call it have been updated to handle the thrown exceptions, including CrudService, ReplicationHandler, and ReplicationService.

refactor the names of these Data Manager implementation classes so that it's easier to use them with the default/local versions of similar. These classes utilize Metacat-specific configuration values rather than relying soley on the bundles that are used in the stand-alone DM lib.

To support GUIDs in MetacatHandler.handleDeleteAction(), I've added in a new method:
deleteFromMetacat() - deletes a document based on the docid
This factors the deletion code out of handleDeleteAction(). handleDeleteAction() now does a docid lookup based on GUID, and if it is not found, reverts to the deletion based on docid instead.

These are fairly significant changes to MetacatHandler.handleInsertOrUpdateAction() that add in support for creation or update of GUIDs and SystemMetadata. Upon insertion or update of DataPackages from non-DataONE aware clients (such as Morpho), the identifier table is updated by creating a GUID, and the systemmetadata table is updated with fields after the EML document is parsed for distribution information and entity typing. System Metadata documents are also generated and inserted into Metacat. The list of data entities is iterated over and System Metadata is generated for each data file as well.

In MetacatHandler I've removed updateSystemMetadata() in favor of additions to insertOrUpdateSystemMetadata(). Modified createSystemMetadata() to reflect the changes as well.

Modified MetacatHandler.createSystemMetadata() to take a localId, not a guid as an argument since there are times when the guid has yet to have been created, and it is created in this method if so.
Also, put the read() call to get the InputStream of the data/metadata document into it's own try/catch statement.

Somehow missed adding in javadoc for read(). Here it is.

For now, getSystemMetadata() will be private like the other *SystemMetadata() methods.

Modified MetacatHandler, updated the getSystemMetadata() method to now use read() and deserializeSystemMetadata() to produce the SystemMetadata object. Exceptions are pushed up the stack, and so accordingly, modified createSystemMetadata() to reflect the changes.

Modified MetacatHandler, added createSystemMetadata() - generates SystemMetadata objects for newly inserted data or documents. This is intended to be used from handleInsertOrUpdateAction(), and only for documents being inserted from clients that don't support the DataONE interface. The method parses EML documents to discover data entities, and updates the system metadata for those entries, with support for describes and describedBy metadata. Currently doesn't handle FGDC, etc. documents....

Modified MetacatHandler, added three methods:
getSystemMetadata() - returns a SystemMetadata object from the systemmetadata table using the given GUID. Stub only.
updateSystemMetadata() - updates the systemmetadata table using the given SystemMetadata object....

Modified MetacatHandler and added two methods:
serializeSystemMetadata() - Serialize a SystemMetadata object to XML string
deserializeSystemMetadata() - Deserialize a SystemMetadata object from an XML string

Modified MetacatHandler, added read() - Read a document from metacat and return an InputStream. The XML or data document should be on disk, but if not, read from the metacat database. This method should be optimized, along with others, to not write stream data to disk for performance reasons.

To support generation of SystemMetadata and GUIDs, added a number of methods to MetacatHandler that are also in CrudService(). CrudService should eventually be refactored to use the handler methods. Added:
readFromFilesystem() - Read a file from Metacat's configured file system data directory, and return a FileInputStream. This code has been factored out of handleInsertOrUpdateAction()....

fixed bug where the wrong checksum alg got written to the db

Updated DROP script that was missing tables and sequences.

added file extension for txt or csv files

To support the generatemissingsystemmetadata REST call, modified CrudService.createSystemMetadata() to use DataoneEMLParser and further determine object formats from EML metadata. Formats currently supported are text/plain, text/csv, image/[jpg|jp2|bmp|tiff|png], and only for EML documents with 'ecogrid://' defined entity urls....

add boolean return to indicate whether or not a property was modified

trying to get the new MMP handler working with ResourceHandler
