Using the Search Tab

Click the Search tab. The Search form opens. The form contains a Select Predefined Query combo box. It also contains a description of the selected query and three buttons:

• Search, which performs the query

• Clear, which clears the form and the Registry Objects area

• Help, which provides help on searching the Registry

The remaining contents of the form depend on which query you select. The default query is Basic Query.

• Select Predefined Query combo box

• Name text field

• Description text field

• ClassificationSchemes tree

The next few sections describe how to use these components.

Selecting a Query

The Select Predefined Query combo box contains the items shown in Table 2–1.

Table 2–1 Predefined Queries

Query Name	Search Purpose
Basic Query	The default generic query, which allows you to search by object type, name, description, and classification
Basic Query - Case Sensitive	Case-sensitive version of Basic Query
FindAllMyObjects	Finds all objects owned (published) by the user who makes the query. May take a long time if the user owns many objects
GetCallersUser	Finds the User object for the user who makes the query
WSDL Discovery Query	Finds Web Services Description Language (WSDL) documents
WSDL Binding Discovery Query	Finds abstract service interfaces protocol bindings described as WSDL Binding definitions
WSDL Port Discovery Query	Finds implementations of service interfaces described as WSDL Port definitions
WSDL PortType Discovery Query	Finds abstract service interfaces described as WSDL PortType definitions
WSDL Service Discovery Query	Finds web services described as WSDL Service definitions

The default selection is Basic Query. The search form for Basic Query and Basic Query — Case Sensitive contains the following components:

• Object Type combo box

• Name text field

• Description text field

• Status combo box

• Select Classification Node button

You can specify any or all of these criteria in a single search. The following sections describe how to perform basic queries:

• Searching by Object Type

• Searching by Name and Description

• Searching by Status

• Searching by Classification

Use the FindAllMyObjects query to search for all the objects that you have published. The query results list all the objects you own except for AuditableEvent objects, which should not be edited or deleted.

Use the GetCallersUser query to view or modify data for the user you created when you registered.

See Performing WSDL Queries for information on using the WSDL queries.

Searching by Object Type

The simplest search is by object type only.

The default choice in the Object Type combo box is RegistryObject, which finds all objects in the Registry. To narrow the search, change the object type.

The ClassificationNode choice lists concepts within classification schemes. ClassificationNode is a synonym for Concept.

Table 2–2 describes the object types available in the Registry.

Table 2–2 Service Registry Object Types

Object Type	Description
AdhocQuery	Represents an ad hoc query expressed in a query syntax. AdhocQuery objects are used for discovery of registry objects. AdhocQuery objects are similar in purpose to the concept of stored procedures in relational databases. For example, the predefined queries in the Search panel are all AdhocQuery objects.
Association	Defines a relationship between two objects.
AuditableEvent	Provides a record of a change to an object. A collection of AuditableEvent objects constitutes an object's audit trail.
Classification	Classifies an object by using a ClassificationScheme.
ClassificationNode	Represents a taxonomy element that has a structural relationship with other elements in an internal ClassificationScheme. Also called a Concept.
ClassificationScheme	Represents a taxonomy used to classify objects. In an internal ClassificationScheme, all taxonomy elements are defined in the registry as Concept instances. In an external ClassificationScheme, the values are not defined in the registry as Concept instances but instead are referenced by their String representations.
ExternalIdentifier	Provides additional information about an object by using String values within an identification scheme (an external ClassificationScheme). Examples of identification schemes are DUNS numbers and Social Security numbers.
ExternalLink	Provides a URI for content that resides outside the registry.
ExtrinsicObject	Provides metadata that describes submitted content whose type is not intrinsically known to the registry and that therefore must be described by means of additional attributes, such as MIME type.
Federation	Represents an affiliated group of registries.
Notification	Represents a notification from the registry regarding an event that matches a Subscription.
Organization	Provides information about an organization. May have a parent, and may have one or more child organizations. Always has a User object as a primary contact, and may offer Service objects.
Person, User	Provides information about persons and registered users within the registry. User objects are affiliated with Organization objects.
Registry	Represents a registry.
RegistryPackage	Represents a logical grouping of any number of registry objects.
Service	Provides information on a service. May contain one or more ServiceBinding objects.
ServiceBinding	Represents technical information on how to access a service.
SpecificationLink	Provides the linkage between a ServiceBinding and a technical specification that describes how to use the service by using the ServiceBinding.
Subscription	Defines a User's interest in certain types of AuditableEvent. A User creates a Subscription in order to receive notification of certain types of events.

To Search by Object Type

1. Choose an object type from the Object Type combo box.

2. Click the Search button, or place the cursor in the Name or Description text field and press Return.

   The search returns all objects of the specified type. You can narrow the search by specifying a name, description, status, or classification.

Searching by Name and Description

You can search for objects by name, by description, or by both.

To Search by Name or Description

1. Type a string in the Name or Description field.

   By default, the search looks for a name or description that matches the entire string that you typed. You can use wildcards to find a range of objects.

   The wildcard characters are percent (%) and underscore (_).

   The percent wildcard matches multiple characters:

   • Type %off% to return names or descriptions that contain the string off, such as Coffee.

   • Type nor% to return names or descriptions that start with Nor or nor, such as North and northern.

   • Type %ica to return names or descriptions that end with ica, such as America.

   The underscore wildcard matches a single character. For example, the search string _us_ would match objects named Aus1 and Bus3.

2. Click the Search button or press Return.

Searching by Status

An object in the Registry can have one of four statuses:

• Approved

• Deprecated

• Submitted

• Withdrawn

The default status of an object in the Registry is Submitted. An object can be approved or deprecated by a Registry administrator or by the owner of the object. An ExtrinsicObject has the status Withdrawn if its repository item has been removed.

To Search by Status

1. Choose a status from the Status combo box.

2. Click the Search button, or place the cursor in the Name or Description text field and press Return.

   The search returns all objects that have the specified status. You can narrow the search by specifying an object type, name, description, or classification.

Searching by Classification

Classification objects classify or categorize objects in the registry by using unique concepts (ClassificationNode objects) that define valid values within a classification scheme. The classification scheme is the parent in a tree hierarchy that contains generations of child concepts. Table 2–3 describes the classification schemes provided by the Registry specifications, which are called canonical classification schemes. Many of the terms in this table are defined in the Registry specifications.

Table 2–3 Canonical Classification Schemes

Classification Scheme Name	Usage	Description or Purpose
AssociationType	Frequently	Defines the types of associations between registry objects. Used as the value of the associationType attribute of an Association instance to describe the nature of the association.
ContentManagementService	Rarely	Defines the types of content management services. Used in the configuration of a content management service, such as a validation or cataloging service.
DataType	Frequently	Defines the data types for object attributes. Used as the value of the slotType attribute of a Slot instance to describe the data type of the Slot value.
DeletionScopeType	Occasionally	Defines the values for the deletionScope attribute of the RemoveObjectsRequest protocol message.
EmailType	Rarely	Defines the types of email addresses.
ErrorHandlingModel	Rarely	Defines the types of error handling models for content management services.
ErrorSeverityType	Rarely	Defines the different error severity types encountered by the Registry while processing protocol messages.
EventType	Occasionally	Defines the types of events that can occur in a registry.
InvocationModel	Rarely	Defines the different ways that a content management service can be invoked by the Registry.
NodeType	Occasionally	Defines the different ways in which a ClassificationScheme can assign the value of the code attribute for its ClassificationNode (Concept) objects.
NotificationOptionType	Rarely	Defines the different ways in which a client can be notified by the registry of an event within a Subscription.
ObjectType	Occasionally	Defines the different types of RegistryObject a registry may support.
PhoneType	Rarely	Defines the types of telephone numbers.
QueryLanguage	Rarely	Defines the query languages supported by the Registry.
ResponseStatusType	Rarely	Defines the different types of status for a RegistryResponse.
StatusType	Occasionally	Defines the different types of status for a RegistryObject.
SubjectGroup	Rarely	Defines the groups that a user can belong to for access control purposes.
SubjectRole	Rarely	Defines the roles that can be assigned to a user for access control purposes.

The primary purpose of the canonical classification schemes is not to classify objects but to provide enumerated types for object attributes. The Registry also contains a number of non-canonical classification schemes, and you can create your own.

To Search by Classification

1. Click the Select Classification Node button.

   The Classification Node Selector window appears.

2. Click the folder icon for the classification scheme you want to use.

   The number in parentheses after each entry indicates how many concepts (ClassificationNode objects) the parent contains.

3. Expand concept nodes beneath the classification scheme until you find the leaf node by which you want to search. A leaf node is a node with no concepts beneath it.

4. Select the leaf node.

5. Click Close in the Classification Node Selector window.

   The ID of the concept you chose appears in a Value text field.

6. Click the Search button, or place the cursor in the Name or Description text field and press Return.

Next Steps

See To Find the WSDL Document for a Service for information on locating the WSDL file associated with the service you found.

To Find the WSDL Document for a Service

After you find a service, you ordinarily want to find the WSDL file associated with the service so that you can use it to create a client proxy to communicate with the service. To do so, follow these steps.

1. Click the Details link for the Service object.

2. Click the Associations tab.

   The Source Object column contains a link named WSDL.

3. Click the WSDL link.

   A Details window appears.

4. Click View Repository Item Content to view the WSDL file.

5. Use your browser's Save As menu item to save the file to your local system.

Viewing Search Results

Objects found by a search appear in the Registry Objects area.

The Registry Objects area consists of the following:

• Buttons that are labeled Apply, Approve, Deprecate, Undeprecate, Bookmark, Relate, Delete, and Set or Change Status, which allow you to perform actions on objects. You must be the object’s creator or a registry administrator to perform any of these actions except for Bookmark.

• A found objects display consisting of a search results table. For most objects, the table contains the following columns:

  • Pick checkbox. Select any two objects to activate the Relate button. See Creating Relationships Between Objects for details. Select one or more objects and click another button to perform that action. An error message appears if you do not have permission to perform the action.

  • Details link. Click this link to open the Details area directly below the Registry Objects area (see Viewing Object Details).

  • Object Type field.

  • Name field.

  • Description field.

  • Version field.

  • Version Comment field.

  • Status field.

For ExtrinsicObject objects, the display has two additional columns: Content Version and Content Version Comment. These columns apply to the repository item for the ExtrinsicObject.

For two kinds of objects, the Version and Version Comment columns are replaced by other content:

• ExternalLink objects: External URI

• ServiceBinding objects: Endpoint

To Use the Bookmark Feature

The Bookmark feature of the user interface allows you to hold one or more objects in the Registry Objects area while you search for other objects. You can then create a relationship between two objects. See Creating Relationships Between Objects for details on how to perform this task.

1. Click Search and execute a query.

2. In the Registry Objects area, select the Pick checkbox for the object or objects that you want to hold there and click the Bookmark button.

   The objects appear in a Bookmarked Objects area above the search results.

3. Execute another query.

Next Steps

When you have finished using a bookmarked object, select the Pick checkbox for the object and click the Remove Bookmark button. The object is removed from the Bookmarked Objects area. If it was the only object in the Bookmarked Objects area, the Bookmarked Objects area disappears.

Viewing Object Details

In the search results table, click the Details link for an object to open the Details area immediately below the Registry Objects area.

This section has a row of buttons and a row of tabs:

• The buttons are Apply, Save, Cancel, Approve, Deprecate, Undeprecate, Delete, and Set or Change Status. The buttons represent actions that you can perform on the object.

• The tabs represent the object’s attributes. The tabs vary depending on the object type.Table 2–4 describes the tabs and the objects they apply to.

Table 2–4 Attribute Tabs in the Details Area

Tab Name	Applies To
Object-Type Detail	All objects (Object-Type is the object type name)
Slots	All objects
Classifications	All objects
External Identifiers	All objects
Associations	All objects
External Links	All objects
Audit Trail	All objects
Postal Addresses	Organization, User
Telephone Numbers	Organization, User
Email Addresses	Organization, User
Users	Organization
Organizations	Organization
Service Bindings	Service
Specification Links	ServiceBinding
Concepts	ClassificationScheme, ClassificationNode
Members	RegistryPackage
Affected Objects	AuditableEvent

Click a tab to find out if the object has any values for the attribute. If it does, click the Details link for the attribute value to open a browser window with the details for the attribute value.

The Associations tab produces a table with three links for each Association:

• Details

• Source Object (the object type is shown)

• Target Object (the object type is shown)

In the Source Object and Target Object columns, the type of the object whose associations you are viewing is shown in bold.

The Audit Trail tab does not produce a table with a Details link. Instead, this tab produces a table that contains the following information:

• The event type

• The date and time of the event

• The name of the User that caused the event

For most objects, the Details area fields are as follows:

• Unique Identifier. For every object, the Unique Identifier is an active link. Click this link to view the XML for the object in a browser window. All registry objects are stored in XML format.

• Logical Unique Identifier. The Logical Unique Identifier is usually the same as the Unique Identifier. If versioning is turned on, the Logical Unique Identifier remains the same for all versions of the object, while the Unique Identifier for the new version receives a suffix that indicates the version number.

• Name

• Description

• Status (usually Submitted, meaning that the object has been published to the Registry)

• Version

• Version Comment

For many objects, the fields are largely self-explanatory (the postal addresses for an Organization, for example). For some objects, the fields require some explanation. The following sections describe these fields.

• Viewing Association Details

• Viewing Classification Scheme Details

• Viewing Extrinsic Object Details

• Viewing External Link Details

Viewing Association Details

The Details area for an Association object contains the following additional fields:

• Source Object and Target Object. For the source and target objects of the association, the panel shows both the name and the object type. The Confirmed By Source Owner checkbox indicates whether or not the association was confirmed or approved by the source object owner. The Confirmed By Target Owner checkbox indicates whether or not the association was confirmed or approved by the target object owner. These checkboxes are always selected for intramural associations.

• Association Type. The combo box displays the selected type of the Association.

• Is Extramural. This checkbox is selected if at least one of the two associated objects is owned by a User other than the User who created the Association. Otherwise, the Association is defined as intramural.

Viewing Classification Scheme Details

The Details area for a ClassificationScheme object contains the following additional fields:

• External Classification Scheme checkbox. This checkbox is selected if the classification scheme is defined outside the Registry (that is, if it has no concepts). An internal classification scheme is a classification scheme whose concept hierarchy is defined within the Registry.

• The Value Type combo box, which contains one of the following selections:

  • Unique. This value indicates that each node of the taxonomy has a unique code assigned to it. This value is the default when you create a classification scheme in Service Registry.

  • Embedded Path. This value indicates that the unique code assigned to each node of the taxonomy also encodes its path.

  • Non-Unique. In some cases nodes are not unique, and it is necessary to use the full path (from the ClassificationScheme to the node of interest) to identify the node. For example, in a geography taxonomy, Moscow could be under both Russia and the USA, where five states have cities that are named Moscow.

Viewing Extrinsic Object Details

The Details area for an ExtrinsicObject object contains the following additional fields:

• Content Version and Content Version Comment. The Details area shows the version and optional comment for the repository item associated with the extrinsic object.

• MimeType. This field contains the MIME type of the extrinsic object.

• Is Opaque? checkbox. This checkbox is selected if the repository item content is not readable by the Registry (for example, if it is encrypted).

• Object Type. This field contains the subconcept within the ObjectType/ExtrinsicObject tree.

• View Content. Click the View Repository Item Content link to view the repository item in a browser window.

Viewing External Link Details

The Details area for an ExternalLink object contains the following additional fields:

• Object Type. This field contains either the ExternalLink object type or a subconcept within the ObjectType/ExtrinsicObject tree.

• Select Concept for Object Type button. Click this button to choose a subconcept within the ObjectType/ExtrinsicObject tree that represents the content of the external URI.

• A Display Content link under the External URI field. Click this link to view the contents of the URI in a browser window.

Using the Explore Tab

The Explore tab allows you to navigate through Registry and Repository content by using the metaphor of a hierarchy of file folders. The root folder, which is named registry, contains all Registry content.

To Use the Explore Tab

1. Click the Explore link.

2. Click the folder labeled registry. This folder contains two subfolders: userData, where all user content is placed, and ClassificationSchemes.

3. Click a link to view the registry objects of that type. Click a folder or expand a node to view the object types at the next level.

To Explore the Classification Schemes

1. Click the ClassificationSchemes folder to open the ClassificationSchemes tree hierarchy in the menu area.

2. Click any link to view that classification scheme in the Registry Objects area.

3. Click a classification scheme folder to see the Concepts beneath it.

   If the Concept icons are folders, they have subconcepts, and you can click the icons to expand them. If the Concept icons are files, they have no subconcepts.

   If the classification scheme folder is a file icon, the classification scheme does not have concepts that are viewable in the Explore area.

4. Click a Concept link to view that concept in the Registry Objects area.

To Explore the UserData Folder

1. Expand the userData node.

2. Expand the RegistryObject node. Do not click the link unless you want to view all registry objects.

3. Click a folder to view the registry objects of that type. Expand a node to view the object types at the next level.
