Methods, apparatus, including computer program products, and systems implement and use techniques relating to electronic signatures. In one implementation, a one-way hash is calculated for an electronic document and a digital watermark representing the one-way hash is embedded in a signature document. Based on a user input, the signature document having the embedded digital watermark is altered, and the electronic document is associated with the signature document. The electronic document and the signature document together comprise a signed electronic document. The user input can include biometric information, such as a handwritten signature or a voice recording. For additional security, the one-way hash can be encrypted before a representation of the hash is embedded in the signature document.

Electronic signing apparatus and methods

Methods and apparatus, including computer program products, for using a meta model for an enterprise service architecture. The meta model includes a first class to represent data organization in a back end data store. The first class includes a data type identifier attribute to permit meta data to identify a data type. The meta model also includes a second class associated with the first class. The second class includes a field identifier attribute to permit meta data to identify fields for a particular data type. The meta model also includes a third class associated with the first class. The third class includes an action identifier attribute to permit meta data to identify an action. In some examples, there is a service provider identifier to permit meta data to identify a service provider class that can effect the action.

Meta model for an enterprise service architecture

Securing documents with electronic signatures

Methods and apparatus, including computer program products, for using dynamic meta data for an enterprise service framework. There is a meta data element associated with a meta data element attribute. A value for the meta data element attribute is calculated in response to a request associated with the meta data element.

Dynamic meta data

Methods and apparatus, including computer program products, for providing input to a workflow application. Source documents are received that have respective original signatures but no digital signatures. The source documents can be paper documents, or they can be scanned representations of paper documents. Proxy digital signatures are applied to digital representations of the source documents. The proxy digital signatures are differentiated in that they are annotated with metadata indicating the quality of the respective original signatures.

Differentiated proxy digital signatures

Methods and apparatus, including computer program products, for processing documents in a workflow system with users external to the system. An electronic document is generated in a workflow system. The electronic document has content and a document appearance, where the appearance represents the content. One or more control codes are generated for the electronic document as part of a workflow in the workflow system, where the control codes are usable to validate the content. A print out including the document appearance and the one or more control codes is created.

Hybrid digital signature workflow

Methods and apparatus, including computer program products, implement techniques for navigating user interface elements of a computer program application. A navigation key press of a navigation key is detected, where the navigation key has a group identifier. A selected group of user interface elements associated with the group identifier is identified. Input focus is shifted to a user interface element in the selected group based on the navigation key.

Generic keyboard navigation

Methods and apparatus, including computer program products, for navigating user interface elements of a computer program application. In one aspect, a method includes grouping user interface elements of an application into groups based on a hierarchical arrangement of the elements, detecting a navigation key press of a sibling or a parent navigation key, and if it is a sibling navigation key, shifting input focus to a next sibling group in the hierarchy, and if it is a parent navigation key, shifting input focus to a parent group in the hierarchy. In another aspect, a method for navigating editable cells of a table includes detecting a forward or a backward navigation key; if it is a forward navigation key, shifting input focus to a next editable cell of the table; and if it is a backward navigation key, shifting input focus to a previous editable cell of the table.

Keyboard navigation in hierarchical user interfaces

Methods and apparatus, including computer program products, for providing services by an application server, the method including collecting a request from a consumer software component for a service from a provider software component, and checking the request against a set of semantic descriptions in a manifest of methods provided by objects in the provider software component.

Service management of a service oriented business framework

Methods and apparatus, including computer program products, for providing information to a screen reader. A method includes the actions of receiving at a client side information for representing a web page in a browser; setting focus initially on an element of the web page and presenting the web page to a user; and in response to a user command directing the focus to an element of the web page, determining whether the element is present in a functionality map, and if so, looking up the element in the functionality map, then processing the element as indicated by a corresponding entry point in the map, and if not, providing the focus and information related to web page elements associated with the focus to a placeholder control, and providing a screen reader with access to the placeholder control.

Matching user interface elements to screen reader functions

Methods and apparatus, including computer program products, for providing information to a screen reader. A method includes the actions of receiving information for representing a web page in a browser; setting focus initially on an element of the web page and presenting the web page to a user; and in response to a user command directing the focus to consecutive target elements of the web page, assigning information related to each target element to a placeholder control and providing a screen reader with access to the placeholder control as the element having focus.

Presenting user interface elements to a screen reader using placeholders

Methods and apparatus, including computer program products implement techniques for validating programs. A language-independent description of a computer program is received, and the language-independent description is validated. The language-independent description includes a definition module and an implementation module. A language-dependent program is generated from the language-independent description, where the language-dependent program includes an interface and a class, and the language-dependent program is validated.

Validating programs

Methods and apparatus, including computer program products, that include representing, in a repository, services from a server, the services including interacting with one or more collections of data elements using a set of operations on the data elements in the collections, the repository comprising descriptions of the collections and common attributes for each collection, the repository organized according to a meta model. The method also includes enabling a software entity to request a service represented in the repository, the service representing a first operation on one or more data elements in a first collection from the collections, and executing the first operation on the one or more data elements in the first collection.

Self-describing business objects

Methods and apparatus, including computer program products, are used to select a renderer. A client identifier is received that identifies a client. The client identifier is a string that is compared with each of one or more client templates, where each client template is associated with one of a plurality of renderers. A score is generated for each comparison, the score reflecting the similarity between the client identifier and the client template. Based on the score, a renderer is selected from the plurality of renderers for use in communication with the client.
