Abstract: Methods and apparatus, including computer program products, implementing and using techniques for providing content management services in a Cloud computing environment. A content management application and associated content is distributed across a set of servers in a Cloud computing environment. Requests for Cloud content management services are received from requesters that are using the Cloud computing environment. The received requests are analyzed to determine an amount of resources needed for responding to the requests. Based on the results of the analysis and a predetermined set of rules, the content management application is dynamically replicated to additional servers within the Cloud computing environment. Any instance of the content management application is capable of replying to any received request so as to maintain a high throughput of the Cloud content management services.

Abstract: Provided are a method, system, and computer program product for a content object encapsulating content items for accessing content and access authorization information. User input of content items is received, wherein each content item indicates a network address and content type of content at the network address. The content items are added to a content object in a computer readable storage. User input is received of access authorization information indicating a user having authority to access the content object. The access authorization information is added to the content object. A user request is received for the content object from a client computer over a network. The access authorization information is processed to determine whether the user at the client computer initiating the request has authorization to access the content object.

User input of content items is received, wherein each content item indicates a network address and content type of content at the network address, content items are added to a content object. User input is received of access authorization information indicating a user having authority to access the content object. The access authorization information is added to the content object. A user request is received for the content object from. The access authorization information is processed to determine whether the user initiating the request has authorization to access the content object. The content object is processed to generate a presentation page to return to the client computer in response to determining that the user of the client computer is authorized to access the content object.

Abstract: Changes to a collection of documents are tracked by generating content information for the collection of documents identifying initial content within the collection of documents and assigning an indicator a value indicating absence of changes to the collection of documents. A change to the collection of documents is detected and the value of the indicator is adjusted in accordance with the detected change to indicate an amount of the initial content within the modified collection of documents.

Abstract: Provided are techniques for managing constraints. Content data and content metadata that is associated with the content data is stored. In response to receiving a change to one of the content data and the content metadata, a provenance value is calculated based on the change, wherein the provenance value represents a change in content between the changed content data or the content metadata and an original version of the content data or the content metadata, and a lineage value is calculated based on the change, wherein the lineage value represents a change in authorship between the changed content data or the content metadata and the original version of the content data or the content metadata. It is determined whether the calculated provenance value violates at least one constraint. It is determined whether the calculated lineage value violates at least one constraint.

Abstract: Methods and apparatus, including computer program products, implementing and using techniques for determining provenance and lineage for content elements in a content management system. An option to track provenance and lineage data for the content element is provided in response to a content element being entered into a content management system. A provenance metadata attribute and a lineage metadata attribute are associated with the content element in response to selecting the option to track provenance and lineage data. An extent of difference is determined between the original content element and the changed content element in response to a change of content being made to the content element. The provenance metadata attribute is updated to reflect the determined extent of difference. It is determined what user changed the content element, and the lineage metadata attribute is updated to reflect the user's involvement in changing the content element.
