Abstract: This document describes tools capable of validating and enabling validation of a package's structure. To do so, constraint grammar is provided that is capable of enabling a person to build a set of machine-readable constraints for a package's structure. Based on this set of constraints, a package validator module may accurately and automatically validate that a package's structure meets these constraints.

Abstract: Data records in files may be validated by sequentially accessing the data records while allowing random data access within a sliding window. The data records may also be validated by caching record values. Variable-length record lists in one or more files may be reduced to fixed length record lists while accessing arbitrary record list items.

Abstract: A relationship data structure associated with a source resource enables methods to discover and describe relationships between the source resource and a plurality of target resources. The relationships are stored in a format independent of the encoding of the source resource. Each relationship between the source resource and the plurality of target resources is stored in a content-neutral format, and the relationship data structure stores, a location of each target resource, a type of relationship with each target resource and an identifier to uniquely identify each relationship between the source resource and each target resource. Accordingly, the relationship data structure allows a decoder to directly discover the relationships between the source resource and the plurality of target resources without decoding the source resource or target resources.

Abstract: Systems and methods for changing items of a computer file, such as an archive file, can include an application programmed to create a file including a first item and a second item, the application storing the file on a storage medium. Systems can also include an input/output module associated with the application, the input/output module retiring the first item upon a change to the first item resulting in an increase or a decrease in a size of the first item. Upon retiring the first item, the input/output module can write a third item at an end of the file, the third item including the change to the first item. Methods can include retiring the first item upon a change to the first item, and writing a third item after the second item, the third item including the change to the first item.

Abstract: Systems and methods for changing items of a computer file can include a storage medium, and an application programmed to create a file including a first item and a second item, the application storing the file on the storage medium, and the first item including padding. The system can also include an input/output module associated with the application, the input/output module being programmed to use at least a portion of the padding of the first item to accommodate a change in a size of the first item. A method can include providing a file including at least a first item and a second item, the first item including padding, changing the first item, and using at least a portion of the padding of the first item to accommodate a change in a size of the first item.

Abstract: A software-based mechanism for taking multimedia notes while using a mobile computing device and synchronizing with a desktop note taking application is provided. A note document containing textual data and objects representing other data types may be synchronized in whole or in part between the two applications. The documents including file formatting of the non-text data may be converted to a preferred format during synchronization.

Abstract: A method for using a web page to perform web-based services on a document of an application program module is provided by one embodiment of the invention. A user editing a document running on an application program module selects to view web-based services that may be performed on the user's document. In response to the user's selection, the application program module hosts a services web page in a dialog box of the application program module using an HTML rendering engine. The services web page may list a number of services or features that may be performed on a user's document. The services may be listed as a number of links. In response to the user selecting one of the services, the HTML rendering engine is directed to the selected web page. The web page script of the selected web page requests that the application program module expose its object model to the web page script.

In response to the user selecting one of the services, the HTML rendering engine is directed to the selected web page. The web page script of the selected web page requests that the application program module expose its object model to the web page script. After verifying any security issues, the application program module sends to the web page script a pointer to its object model.
