As of release 1.7, DSpace supports running curation tasks, which are described in this section. DSpace 1.7 and subsequent distributions will bundle (include) several useful tasks, but the system also is designed to allow new tasks to be added between releases, both general purpose tasks that come from the community, and locally written and deployed tasks.

Changes in 1.8
- New package: The default curation task package is now org.dspace.ctask. The tasks supplied with DSpace releases are now under org.dspace.ctask.general
- New tasks in DSpace release: Some additional curation tasks have been supplied with DSpace 1.8, including a link checker and a translator
- UI task groups: Ability to assign tasks to groups whose members display together in the Administrative UI
- Task properties: Support for a site-portable system for configuration and profiling of tasks using configuration files
- New framework services: Support for context management during curation operations
- Scripted tasks: New (experimental) support for authoring and executing tasks in languages other than Java
...
The goal of the curation system ('"CS'") is to provide a simple, extensible way to manage routine content operations on a repository. These operations are known to CS as '"tasks'", and they can operate on any DSpaceObject (i.e. subclasses of DSpaceObject) - which means the entire Site, Communities, Collections, and Items - viz. core data model objects. Tasks may elect to work on only one type of DSpace object - typically an Item - and in this case they may simply ignore other data types (tasks have the ability to '"skip' " objects for any reason). The DSpace core distribution will provide a number of useful tasks, but the system is designed to encourage local extension - tasks can be written for any purpose, and placed in any java package. This gives DSpace sites the ability to customize the behavior of their repository without having to alter - and therefore manage synchronization with - the DSpace source code. What sorts of activities are appropriate for tasks?
...
Since tasks have access to, and can modify, DSpace content, performing tasks is considered an administrative function to be available only to knowledgeable collection editors, repository administrators, sysadmins, etc. No tasks are exposed in the public interfaces.
Activation
...
For CS to run a task, the code for the task must of course be included with other deployed code (to {{\[dspace
\]/lib
}}, WAR, etc) but it must also be declared and given a name. This is done via a configuration property in {{\[dspace
\]/config/modules/curate.cfg
}} as follows:
Code Block |
---|
plugin.named.org.dspace.curate.CurationTask = \
org.dspace.ctask.general.NoOpCurationTask = noop, \
org.dspace.ctask.general.ProfileFormats = profileformats, \
org.dspace.ctask.general.RequiredMetadata = requiredmetadata, \
org.dspace.ctask.general.ClamScan = vscan, \
org.dspace.ctask.general.MicrosoftTranslator = translate, \
org.dspace.ctask.general.MetadataValueLinkChecker = checklinks
|
For each activated task, a key-value pair is added. The key is the fully qualified class name and the value is the taskname used elsewhere to configure the use of the task, as will be seen below. Note that the curate.cfg configuration file, while in the config directory, is located under '"modules'". The intent is that tasks, as well as any configuration they require, will be optional '"add-ons' " to the basic system configuration. Adding or removing tasks has no impact on dspace.cfg.unmigrated-wiki-markup
For many tasks, this activation configuration is all that will be required to use it. But for others, the task needs specific configuration itself. A concrete example is described below, but note that these task-specific configuration property files also reside in {{\[dspace
\]/config/modules
}}
Writing your own tasks
A task is just a java class that can contain arbitrary code, but it must have 2 properties:
...
Second, it must implement the interface '"org.dspace.curate.CurationTask'"
The CurationTask interface is almost a '"tagging' " interface, and only requires a few very high-level methods be implemented. The most significant is:
Code Block | ||
---|---|---|
| ||
int perform(DSpaceObject dso); |
...
Tasks are invoked using CS framework classes that manage a few details (to be described below), and this invocation can occur wherever needed, but CS offers great versatility '"out of the box'":
On the command line
A simple tool '"CurationCli' " provides access to CS via the command line. This tool bears the name '"curate' " in the DSpace launcher. For example, to perform a virus check on collection '"4'":
Code Block |
---|
[dspace]/bin/dspace curate -t vscan -i 123456789/4 |
The complete list of arguments:
Code Block |
---|
-t taskname: name of task to perform
-T filename: name of file containing list of tasknames
-e epersonID: (email address) will be superuser if unspecified
-i identifier: Id of object to curate. May be (1) a handle (2) a workflow Id or (3) 'all' to operate on the whole repository
-q queue: name of queue to process - -i and -q are mutually exclusive
-l limit: maximum number of objects in Context cache. If absent, unlimited objects may be added.
-s scope: declare a scope for database transactions. Scope must be: (1) 'open' (default value) (2) 'curation' or (3) 'object'
-v emit verbose output
-r - emit reporting to standard out
|
...
In the XMLUI, there are several ways to execute configured Curation Tasks:
- From the '"Curate' " tab that appears on each '"Edit Community/Collection/Item' " page: this tab allows an Administrator, Community Administrator or Collection Administrator to run a Curation Task on that particular Community, Collection or Item. When running a task on a Community or Collection, that task will also execute on all its child objects, unless the Task itself states otherwise (e.g. running a task on a Collection will also run it across all Items within that Collection).
- NOTE: Community Administrators and Collection Administrators can only run Curation Tasks on the Community or Collection which they administer, along with any child objects of that Community or Collection. For example, a Collection Administrator can run a task on that specific Collection, or on any of the Items within that Collection.
- From the Administrator's '"Curation Tasks' " page: This option is only available to DSpace Administrators, and appears in the Administrative side-menu. This page allows an Administrator to run a Curation Task across a single object, or all objects within the entire DSpace site.
- unmigrated-wiki-markup
- In order to run a task from this interface, you must enter in the handle for the DSpace object. To run a task site-wide, you can use the handle: {{\
[your-handle-prefix
\]/0
}}
- In order to run a task from this interface, you must enter in the handle for the DSpace object. To run a task site-wide, you can use the handle: {{\
...
Each of the above pages exposes a drop-down list of configured tasks, with a button to 'perform' the task, or queue it for later operation (see section below). Not all activated tasks need appear in the Curate tab - you filter them by means of a configuration property. This property also permits you to assign to the task a more user-friendly name than the PluginManager _taskname_. The property resides in {{\[dspace
\]/config/modules/curate.cfg
}}:
Code Block |
---|
ui.tasknames = \
profileformats = Profile Bitstream Formats, \
requiredmetadata = Check for Required Metadata
|
When a task is selected from the drop-down list and performed, the tab displays both a phrase interpreting the '"status code' " of the task execution, and the '"result' " message if any has been defined. When the task has been queued, an acknowledgement appears instead. You may configure the words used for status codes in curate.cfg (for clarity, language localization, etc):
Code Block |
---|
ui.statusmessages = \
-3 = Unknown Task, \
-2 = No Status Set, \
-1 = Error, \
0 = Success, \
1 = Fail, \
2 = Skip, \
other = Invalid Status
|
...
- a task can appear in more than one group if desired
- tasks that belong to no group are invisible to the admin UI (but of course available in other contexts of use)
...
The configuration of groups follows the same simple pattern as tasks, using properties in {{\[dspace
\]/config/modules/curate.cfg
}}. The group is assigned a simple logical name, but also a localizable name that appears in the UI. For example:
Code Block |
---|
# ui.taskgroups contains the list of defined groups, together with a pretty name for UI display
ui.taskgroups = \
replication = Backup and Restoration Tasks, \
integrity = Metadata Integrity Tasks, \
.....
# each group membership list is a separate property, whose value is comma-separated list of logical task names
ui.taskgroup.integrity = profileformats, requiredmetadata
....
|
In workflow
...
CS provides the ability to attach any number of tasks to standard DSpace workflows. Using a configuration file {{\[dspace
\]/config/workflow-curation.xml
}}, you can declaratively (without coding) wire tasks to any step in a workflow. An example:
Code Block | ||
---|---|---|
| ||
<taskset-map> <mapping collection-handle="default" taskset="cautious" /> </taskset-map> <tasksets> <taskset name="cautious"> <flowstep name="step1"> <task name="vscan"> <workflow>reject</workflow> <notify on="fail">$flowgroup</notify> <notify on="fail">$colladmin</notify> <notify on="error">$siteadmin</notify> </task> </flowstep> </taskset> </tasksets> |
This markup would cause a virus scan to occur during step one of workflow for any collection, and automatically reject any submissions with infected files. It would further notify (via email) both the reviewers (step 1 group), and the collection administrators, if either of these are defined. If it could not perform the scan, the site administrator would be notified.unmigrated-wiki-markup
The notifications use the same procedures that other workflow notifications do - namely email. There is a new email template defined for curation task use: {{\[dspace
\]/config/emails/flowtask_notify
}}. This may be language-localized or otherwise modified like any other email template.
Tasks wired in this way are normally performed as soon as the workflow step is entered, and the outcome action (defined by the 'workflow' element) immediately follows. It is also possible to delay the performance of the task - which will ensure a responsive system - by queuing the task instead of directly performing it:
Code Block | ||
---|---|---|
| ||
... <taskset name="cautious"> <flowstep name="step1" queue="workflow"> ... |
This attribute (which must always follow the '"name' " attribute in the flowstep element), will cause all tasks associated with the step to be placed on the queue named '"workflow' " (or any queue you wish to use, of course), and further has the effect of suspending the workflow. When the queue is emptied (meaning all tasks in it performed), then the workflow is restarted. Each workflow step may be separately configured,
...
If these pre-defined ways are not sufficient, you can of course manage curation directly in your code. You would use the CS helper classes. For example:
Code Block | ||
---|---|---|
| ||
Collection coll = (Collection)HandleManager.resolveToObject(context, "123456789/4");
Curator curator = new Curator();
curator.addTask("vscan").curate(coll);
System.out.println("Result: " + curator.getResult("vscan"));
|
would do approximately what the command line invocation did. the method '"curate' " just performs all the tasks configured
configured (you can add multiple tasks to a curator).
...
Because some tasks may consume a fair amount of time, it may not be desirable to run them in an interactive context. CS provides a simple API and means to defer task execution, by a queuing system. Thus, using the previous example:
Code Block | ||
---|---|---|
| ||
Curator curator = new Curator();
curator.addTask("vscan").queue(context, "monthly", "123456789/4");
|
...
use the command-line tool, but we could also read the queue programmatically. Any number of queues can be defined and used as needed.
In the administrative UI curation '"widget'", there is the ability to both perform a task, but also place it on a queue for later processing.
...
Few assumptions are made by CS about what the 'outcome' of a task may be (if any) - it. could e.g. produce a report to a temporary file, it could modify DSpace content silently, etc. But the CS runtime does provide a few pieces of information whenever a task is performed:
...
This was mentioned above. This is returned to CS whenever a task is called. The complete list of values:
Code Block |
---|
-3 NOTASK - CS could not find the requested task -2 UNSET - task did not return a status code because it has not yet run -1 ERROR - task could not be performed 0 SUCCESS - task performed successfully 1 FAIL - task performed, but failed 2 SKIP - task not performed due to object not being eligible |
...
The task may define a string indicating details of the outcome. This result is displayed, in the '"curation widget' " described above:
Code Block |
---|
"Virus 12312 detected on Bitstream 4 of 1234567789/3"
|
CS does not interpret or assign result strings, the task does it. A task may not assign a result, but the '"best practice' " for tasks is to assign one whenever possible.
...
The status code, and the result string are accessed (or set) by methods on the Curation object:
Code Block | ||
---|---|---|
| ||
Curator curator = new Curator(); curator.addTask("vscan").curate(coll); int status = curator.getStatus("vscan"); String result -= curator.getResult("vscan"); |
Task Properties
...
DSpace 1.8 introduces a new '"idiom' " for tasks that require configuration data. It is available to any task whose implementation extends _AbstractCurationTask
_, but is completely optional. There are a number of problems that task properties are designed to solve, but to make the discussion concrete we will start with a particular one: the problem of hard-coded configuration file names. A task that relies on configuration data will typically encode a fixed reference to a configuration file name. For example, the virus scan task reads a file called '"clamav.cfg
'", which lives in {{\[dspace
\]/config/modules
}}. And thus in the implementation one would find:
Code Block | ||
---|---|---|
| ||
host = ConfigurationManager.getProperty("clamav", "service.host");
|
...
Task properties gives us a simple solution. Here is how it works: suppose that both colliding tasks instead use this method provided by AbstractCurationTask in their task implementation code (e.g. in virus scanner):
Code Block | ||
---|---|---|
| ||
host = taskProperty("service.host");
|
Note that there is no name of the configuration file even mentioned, just the property name whose value we want. At runtime, the curation system resolves this call to a configuration file, and it uses the name the task has been configured as as the name of the config file. So, for example, if both were installed (in curate.cfg
) as:
Code Block |
---|
org.dspace.ctask.general.ClamAv = vscan,
org.community.ctask.ConflictTask = virusscan,
....
|
...
then '"taskProperty()
' " will resolve to {{\[dspace
\]/config/modules/vscan.cfg
}} when called from ClamAv task, but {{\[dspace
\]/config/modules/virusscan.cfg
}} when when called from ConflictTask's code. Note that the '"vscan
' " etc are locally assigned names, so we can always prevent the 'collisions'mentioned, and we make the tasks much more portable, since we remove the 'hard-coding' of config "collisions" mentioned, and we make the tasks much more portable, since we remove the "hard-coding" of config names.
The entire '"API' " for task properties is:
Code Block | ||
---|---|---|
| ||
public String taskProperty(String name);
public int taskIntProperty(String name, int defaultValue);
public long taskLongProperty(String name, long defaultValue);
public boolean taskBooleanProperty(String name, boolean default);
|
...
Another use of task properties is to support multiple task profiles. Suppose we have a task that we want to operate in one of two modes. A good example would be a mediafilter task that produces a thumbnail. We can either create one if it doesn't exist, or run with '"-force' " which will create one regardless. Suppose this behavior was controlled by a property in a config file. If we configured the task as '"thumbnail'", then we would have in {{\[dspace
\]/config/modules/thumbnail.cfg
}}:
Code Block |
---|
...other properties...
thumbnail.maxheight = 80
thumbnail.maxwidth = 80
forceupdate=false
|
Then, following the pattern above, the thumbnail generating task code would look like:
Code Block | ||
---|---|---|
| ||
if (taskBooleanProperty("forceupdate")) { // do something } |
But an obvious use-case would be to want to run force mode and non-force mode from the admin UI on different occasions. To do this, one would have to stop Tomcat, change the property value in the config file, and restart, etc However, we can use task properties to elegantly rescue us here. All we need to do is go into the config/modules directory, and create a new file called: thumbnail.force.cfg
. In this file, we put only one property:
Code Block |
---|
forceupdate=true
|
Then we add a new task (really just a new name, no new code) in curate.cfg:
Code Block |
---|
org.dspace.ctask.general.ThumbnailTask = thumbnail,
org.dspace.ctask.general.ThumbnailTask = thumbnail.force
|
Consider what happens: when we perform the task '"thumbnail
' " (using taskProperties), it reads the config file thumbnail.cfg and operates in '"non-force' " profile (since the value is false), but when we run the task '"thumbnail.force
' " the curation system first reads thumbnail.cfg
, then reads thumbnail.force.cfg
which overrides the value of the '"forceupdate
' " property. Notice that we did all this via local configuration - we have not had to touch the source code at all to obtain as many '"profiles' " as we would like.
Task Annotations
CS looks for, and will use, certain java annotations in the task Class definition that can help it invoke tasks more intelligently. An example may explain best. Since tasks operate on DSOs that can either be simple (Items) or containers (Collections, and Communities), there is a fundamental problem or ambiguity in how a task is invoked: if the DSO is a collection, should the CS invoke the task on each member of the collection, or does the task '"know' " how to do that itself? The decision is made by looking for the @Distributive annotation: if present, CS assumes that the task will manage the details, otherwise CS will walk the collection, and invoke the task on each member. The java class would be defined:
Code Block | ||
---|---|---|
| ||
@Distributive
public class MyTask implements CurationTask
|
A related issue concerns how non-distributive tasks report their status and results: the status will normally reflect only the last invocation of the task in the container, so important outcomes could be lost. If a task declares itself @Suspendable, however, the CS will cease processing when it encounters a FAIL status. When used in the UI, for example, this would mean that if our virus scan is running over a collection, it would stop and return status (and result) to the scene on the first infected item it encounters. You can even tune @Supendable tasks more precisely by annotating what invocations you want to suspend on. For example:
Code Block | ||
---|---|---|
| ||
@Suspendable(invoked=Curator.Invoked.INTERACTIVE)
public class MyTask implements CurationTask
|
...
Only a few annotation types have been defined so far, but as the number of tasks grow, we can look for common behavior that can be signaled by annotation. For example, there is a @Mutative type: that tells CS that the task may alter (mutate) the object it is working on.
Scripted Tasks
Info |
---|
The procedure to set up curation tasks in Jython is described on a separate page: Curation tasks in Jython |
DSpace 1.8 includes limited (and somewhat experimental) support for deploying and running tasks written in languages other than Java. Since version 6, Java has provided a standard way (API) to invoke so-called scripting or dynamic language code that runs on the java virtual machine (JVM). Scripted tasks are those written in a language accessible from this API. The exact number of supported languages will vary over time, and the degree of maturity of each language, or suitability of the language for curation tasks will also vary significantly. However, preliminary work indicates that Ruby (using the JRuby runtime) and Groovy may prove viable task languages.unmigrated-wiki-markup
Support for scripted tasks does *not* include any DSpace pre-installation of the scripting language itself - this must be done according to the instructions provided by the language maintainers, and typically only requires a few additional jars on the DSpace classpath. Once one or more languages have been installed into the DSpace deployment, task support is fairly straightforward. One new property must be defined in {{\[dspace
\]/config/modules/curate.cfg
}}:
Code Block |
---|
script.dir = ${dspace.dir}/scripts
|
This merely defines the directory location (usually relative to the deployment base) where task script files should be kept. This directory will contain a '"catalog' " of scripted tasks named task.catalog
that contains information needed to run scripted tasks. Each task has a 'descriptor' property with value syntax:
<engine>|<relFilePath>|<implClassCtor>
An example property for a link checking task written in Ruby might be:
...
This descriptor means that a '"ruby
' " script engine will be created, a script file named '"rubytask.rb
' " in the directory <script<script.
dir> dir
> will be loaded and the resolver will expect an evaluation of '"LinkChecker.new
' " will provide a correct implementation object. Note that the task must be configured in all other ways just like java tasks (in ui.tasknames, ui.taskgroups
, etc).
Script files may embed their descriptors to facilitate deployment. To accomplish this, a script must include the descriptor string with syntax:
$td=<descriptor>
somewhere on a comment line. For example:
Code Block |
---|
# My descriptor $td=ruby|rubytask.rb|LinkChecker.new
|
For reasons of portability, the <relFilePath> component may be omitted in this context. Thus, '"$td=ruby||LinkChecker.new
' " will be expanded to a descriptor with the name of the embedding file.
Interface
Scripted tasks must implement a slightly different interface than the CurationTask interface used for Java tasks. The appropriate interface for scripting tasks is ScriptedTask and has the following methods:
Code Block | ||
---|---|---|
| ||
public void init(Curator curator, String taskId) throws IOException; public int performDso(DSpaceObject dso) throws IOException; public int performId(Context ctx, String id) throws IOException; int performId(Context ctx, String id) throws IOException; |
The difference is that ScriptedTask has separate perform methods for DSO and identifier. The reason for that is that some scripting languages (e.g. Ruby) don't support method overloading.
performDso() vs. performId()
You may have noticed that the ScriptedTask
interface has both performDso()
and performId()
methods, but only performDso is ever called when curator is launched from command line.
There are a class of use-cases in which we want to construct or create new DSOs (DSpaceObject) given an identifier in a task. In these cases, there may be no live DSO to pass to the task.
You actually can get curation system to call performId()
if you queue a task then process the queue - when reading the queue all CLI has is the handle to pass to the task.
Starter Tasks
DSpace 1.7 bundles a few tasks and activates two (2) by default to demonstrate the use of the curation system. These may be removed (deactivated by means of configuration) if desired without affecting system integrity. Each task is briefly described here.
...
The task with the taskname 'formatprofiler' (in the admin UI it is labeled "Profile Bitstream Formats") examines all the bitstreams in an item and produces a table ("profile") which is assigned to the result string. It is activated by default, and is configured to display in the administrative UI. The result string has the layout:
Code Block |
---|
10 (K) Portable Network Graphics
5 (S) Plain Text
|
where the left column is the count of bitstreams of the named format and the letter in parentheses is an abbreviation of the repository-assigned support level for that format:
Code Block |
---|
U Unsupported
K Known
S Supported
|
The profiler will operate on any DSpace object. If the object is an item, then only that item's bitstreams are profiled; if a collection, all the bitstreams of all the items; if a community, all the items of all the collections of the community.
Required Metadata
The '"requiredmetadata
' " task examines item metadata and determines whether fields that the web submission (input-forms.xml
) marks as required are present. It sets the result string to indicate either that all required fields are present, or constructs a list of metadata elements that are required but missing. When the task is performed on an item, it will display the result for that item. When performed on a collection or community, the task be performed on each item, and will display the last item result. If all items in the community or collection have all required fields, that will be the last in the collection. If the task fails for any item (i.e. the item lacks all required fields), the process is halted. This way the results for the 'failed' items are not lost.
Virus Scan
The '"vscan
' " task performs a virus scan on the bitstreams of items using the ClamAV software product.
Clam AntiVirus is an open source (GPL) anti-virus toolkit for UNIX. A port for Windows is also available. The virus scanning curation task interacts with the ClamAV virus scanning service to scan the bitstreams contained in items, reporting on infection(s). Like other curation tasks, it can be run against a container or item, in the GUI or from the command line. It should be installed according to the documentation at http://www.clamav.net. It should not be installed in the dspace installation directory. You may install it on the same machine as your dspace installation, or on another machine which has been configured properly.
...
This plugin requires a ClamAV daemon installed and configured for TCP sockets. Instructions for installing ClamAV (http://www.clamav.net/doc/latest/clamdoc.pdf)
NOTICE: The following directions assume there is a properly installed and configured clamav daemon. Refer to links above for more information about ClamAV.
The Clam anti-virus database must be updated regularly to maintain the most current level of anti-virus protection. Please refer to the ClamAV documentation for instructions about maintaining the anti-virus database.
