Questions?

Questions?• Do we need BMContentLightType?• BMContentType inheritance from BMContentLightType and move

BMContentLightType to baseMediaService.xsd.• Changing baseMediaService effect on previous fims versions

implementation and rules for fims XSD(s) versioning.• RepositoryProfileType: rename to something more generic and

descriptive, like CredentialsProfile or AuthorizationProfile. Its scope can exceed the Repository and be used in other services. Perhaps, it should even live in the baseMediaService.xsd.

• Do we need UpdateStatus operation?

Questions?• Will the Lock operation on an object - BMContentType locks the

associated contents – BMEssenceLocatorType?• ResourceIDType as a parameter – REST.• Many classes inheriting from bms:Resource – REST.• I understand that if my repository exposes a custom searchable and

updateable property it should be returned in GetSchemaExtensions, GetUpdatableProperties and GetSearchableProperties. Is this correct?

Questions?• What about "FIMS standard" supported properties (the ones defined

in description-V1_0_7.xsd)? Should we also return them in GetSchemaExtensions, GetUpdatableProperties and GetSearchableProperties?

• Could we also expose standard FIMS technical metadata to be used in the searches? (For example, "title = NY and aspect_ratio = 16/9")

Questions?• Locking is an optional feature, the token parameter should be

optional in ReplaceObjectRequest, UpdatePropertiesRequest and DeleteContentRequest - DONE.

• Should we add a lock token to DeleteObjectRequestType?• Naming can be confusing at first sight. The functions and structures

that deal with "BMContent" use "Object" and the ones that deal with "EssenceLocator" use "Content", which could be thought as BMContent. For coherence, the GetBMContent(s) functions should be GetObject(s) and RetrieveBMEssence() should be RetrieveContent()

Questions?• QueryParameteType.valueType and

RepositorySearchablePropertyInfoType.dataType, I am not sure if specifying datatypes by name using a string can create interoperatibility problems. Perhaps we should define and use a Resource "DataType" and provide a list of well-known fims data types, which could be extended by inheritance.

• Do we plan to have a way of extending QueryParameterOperand with custom operands? It would be desirable. enumeration vs. object (resource) in xsd.

Questions?• Purge Operations – Rename• Delete operations - Rename• AddObject – Rename• AddContent – Rename (RegisterContent)• Responses that contain BMContentType can we have an option in

the content to return BMContentLightType instead. The use of container object with “choice” would this be a good represntation.

• RCR to define max. lock expiration duration (seconds, minutes, hours?) allowed by the system, null means no restriction.

Questions?• RetrieveOpenLocks operation – Rename• RCR to define if dirty read allowed• When a parent is locked will this lock the children?• Do we need GetBMContentor GetBMContents should be enough?

Questions/AnswersFeedback & Follow Up Items

2. Revisit requests to add which form of BMContentType should be returned in the responses (where applicable), full or light Done

» A new optional Boolean (returnFullBMContent), default is True.» Some requests may change to the form of an envelope for multiple input

parameters. (ASH)

3. Responses that contain BMContentType can we have an option in the content to return BMContentLightType instead. Will the use of container object with “choice” be a good representation? Done

» This can be solved by the use of BMContentType with min. properties, and setting the (isFullyPopulated) property as discussed.

Decision for 1 - 2 - 3: BMContentType is not neededAll repository operations use the BMContentType object as input or output parameter to represent a media asset. The object can be used in its minimal form (IDs) or fully hydrated The ability to describe information populated within FIMS objects is needed to differentiate between data not hydrated and data not existing. The proposal includes the addition of a property to the ResourceReferenceType. The new optional IsFullyPopulated property is set to true when all of the properties of an object are populated with all available existing data.The capability of defining as an input parameter what information is being returned as part of a query or get operation is still handled by selecting an enumeration of type QueryResultInfoType. The same concept will be added to Get operation.

4. Changing baseMediaService effect on previous fims versions implementation and rules for fims XSD(s) versioning

» (TECHNICAL BOARD) Will be implemented as part of V1.08

5. Figuring proper naming for Object, Essence and BMContent = (Object + Essence) representation and usage.

» There is a need for a smaller group to discuss, document and publish. (TECHNICAL BOARD) Will setup a separate meeting to include FIMS REP + Tech

Decision: Will be implemented as part of V 1.08Decision: Will be implemented as part of V 1.08

Decision: A sub group including members of FIMS REP and FIMS TECH will work on this taskDecision: A sub group including members of FIMS REP and FIMS TECH will work on this task

Decision: Keep the 2 operations but rename GetBMContents to possibly GetBMContentCollectionDecision: Keep the 2 operations but rename GetBMContents to possibly GetBMContentCollection

12. RepositoryProfileType - Rename to something more generic and descriptive, like Credentials or Authorization Profile.

» More discussion, concern on why don't we make use of the http security! (REPOSITORY GROUP TECHNICAL BOARD) Will setup a separate meeting to include FIMS REP + Tech

13.RepositoryProfileType scope can exceed the Repository and be used in other services. Perhaps, it should even live in the baseMediaService.xsd.

» (REPOSITORY GROUP) To bring up again with Tech Group/Adm Group

14.Will the Lock operation on an object – BMContentType locks the associated contents – BMEssenceLocatorType? When a parent is locked will this lock the children?

» Best practice, expected behavior(documentation) (REPOSITORY GROUP) Should be added to RCR

Decision: Keep the 2 operations but rename GetBMContents to possibly GetBMContentCollectionDecision: Keep the 2 operations but rename GetBMContents to possibly GetBMContentCollection

Decision: Bring this up again with Tech and Adm groups as it may break interface definition for operations in V1.07Decision: Bring this up again with Tech and Adm groups as it may break interface definition for operations in V1.07

Decision: Locking behavior will be described in a new RCR parameter. The default and recommended behavior is cascading locks

15 .Locking is an optional feature; the token parameter should be optional in ReplaceObjectRequest, UpdatePropertiesRequest and DeleteContentRequest.

» DONE (ASH) Done

16.Should we add a lock token to DeleteObjectRequestType?» Add to DeleteObjectRequestType (ASH) We are adding the lock to this operation

17.Do we need UpdateStatus operation?» Remove it (ASH) TAKE IT OUT

18.ResourceIDType - REST concern on usage as input parameter.» REST group will investigate.» Remove it and use ResourceReferenceType. (ASH) » Remove ResourceIDType and use ResourceReferenceType for all parameters

(input and output)

Decision: Parameter will be made optionalDecision: Parameter will be made optional

Decision: Token will be added to this operationDecision: Token will be added to this operation

Decision: Operation to be removedDecision: Operation to be removed

18.ResourceIDType - REST concern on usage as input parameter.» REST group will investigate.» Remove it and use ResourceReferenceType. (ASH)

Decision: Remove ResourceIDType and use ResourceReferenceType for all parameters (input and output)

19.Many classes inheriting from ResourceType (REST) is it overdone?» It is a cautious approach. However, we should have another cleaning

pass. (ASH)

- Decision:

- Make not-a-Resource the following classes. Make something a Resource if it makes sense to perform operations on it (mainly CRUD) or to access it by reference. The cost of making something to be a resource is to pass a mandatory ResourceID in every use, which is not negligible IMHO.- PropertyInfo: Seems a one-shot structure. - RepositoryProfile: which would the meaning of the ResourceID be in a login/password pair or in a security token?- QueryInputDefinition: As it includes the pageNumber, it does not seem possible to reuse a stored

Decision: - Make not-a-Resource the following classes. Make something a Resource if it makes sense to perform operations on it (mainly CRUD) or to access it by reference. The cost of making something to be a resource is to pass a mandatory ResourceID in every use, which is not negligible IMHO.- PropertyInfo: Seems a one-shot structure. - RepositoryProfile: which would the meaning of the ResourceID be in a login/password pair or in a security token?- QueryInputDefinition: As it includes the pageNumber, it does not seem possible to reuse a stored

Decision: QueryInputDefinition, which would be the only reason I can figure out for making this a resource- QueryGroup: No persistence by itself (but as a QueryExpression) and no operations- QueryParameter: Same reasonQueryExpression: I would keep it as a resource if and only if we find sense in saving a query for later recalling. In this use case, it should be enough with passing just the ResourceReference and not the fully populated QueryExpression. The drawback is the need to pass a ResourceID in every query, despite it is a stored one or a volatile one. Perhaps the EmptyID could be used for one-shot queries- QueryResultSorting: Same case then QueryExpression- QueryOutputDefinition: Same case then QueryExpression- QueryProfileType: Same case then QueryExpression

20.Recheck for min occurrence = 0, when inheritance from ResourceType» (ASH) Still need to do the pass, task assigned to Ash

21.QueryParameterType.valueType and RepositorySearchablePropertyInfoType.dataType, specifying datatypes by name using a string can create interoperatibility problems. Perhaps we should define and use a Resource "DataType" and provide a list of well-known fims data types, which could be extended by inheritance.

Decision: Another pass will be done. Task assigned to AshDecision: Another pass will be done. Task assigned to Ash

Decision: It can be removed from QueryParameterType as it is included and retrievable from RepositorySearchablePropertyInfosType

Decision for 22 and 23: leverage an extension model for complex scenarios but use simple existing object for simple usecases. The next 5 slides describe the places where the extension model should be applied

24. RCR to define max. Lock expiration duration (seconds, minutes, and hours?) allowed by the system, null means no restriction.

» Add to General Repository Capabilities, XSD Time element. (ASH)

25. RCR to define if dirty read allowed.» Add to general Capabilities. (ASH) Done , should be fully described in doc specs

26. RCR to define if , if it supports case sensitivity query.» Add to general Capabilities. (ASH) add it

27.QueryParameterType: Add a Boolean (optional) to ignore case sensitivity.» Add to QueryParameterType. (ASH) will wait for decision on operand to make a

final decision

Decision: Add to General Repository Capabilities, XSD Time elementDecision: Add to General Repository Capabilities, XSD Time element

Decision: Add to General Repository Capabilities. Should also be described in details in implementation guideline Decision: Add to General Repository Capabilities. Should also be described in details in implementation guideline

Decision: Add to General Repository Capabilities.Decision: Add to General Repository Capabilities.

Decision: Add property to QueryParameterTypeDecision: Add property to QueryParameterType

28. Query XML representation» Compound Query.xml (Repository Group) » query-new.xml (Zsolt – Harris)

29.Repository Events: Confusing pattern, may be overdone and needs to be simplified and to the point. Revisit, consolidate the Repository Asset Events

» Events Discussion and clear documentation needed. (REPOSITORY GROUP) Frank will propose something for next week meeting as simplified design for eventing model. Group please send infos to Frank

Decision: Keep existing modelDecision: Keep existing model

30.Check with REST team if we need to add the word Repository at the beginning of each Request/Response.

Decision: To be addressed during the renaming exercise as members of the REST group will be present.Decision: To be addressed during the renaming exercise as members of the REST group will be present.
