A computer program listing appendix on compact disc is included in the application. The computer program listing appendix includes sample schema files (“.XSD”) representing aspects (for example) of a word processing application and associated documents described herein.
The extensible markup language (XML) format being introduced and now widely adopted has been transforming the landscape of computer programming. XML has a number of advantages over previous programming languages.
The XML format is considered an accessible format that allows other developers to see the storage details (such as data types, restrictions, relationships, values, and the like) of content represented in such a format. The interoperability of XML programs is also an advantage. Solutions can alter information inside a document or create a document entirely from scratch by using standard tools and technologies capable of manipulating XML.
Many documents today are authored using proprietary software that stores the documents in proprietary formats. The proprietary formats render the documents difficult to read by other programs, whether the programs are different kinds of programs (such as spreadsheet or word processors) or written by different vendors.
Furthermore the proprietary formats make it difficult to control the ownership of data (for example, by retaining data in the file even after it is deleted. It is also often difficult to ensure uniformity when sharing data between documents authored by differing application types because the document files have different formats. Even merely trying to identify what data is stored in a proprietary format can be difficult.
This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the detailed description. This summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended as an aid in determining the scope of the claimed subject matter.
The present disclosure is directed to providing a transparent format for content (such as text) of shape objects whereby documents authored by different types of applications can uniformly share information. Shape objects comprise, for example, text that has properties such as font, style, color, size and the like. Text can be embodiment in text objects that can be used to represent individual characters, text runs, paragraphs, and the like. Characters can comprise ASCII codes, Asian characters, and the like.
The text runs are hierarchically represented such that principles of object oriented programming can be applied to the text run properties. For example, elements and attributes can be created in a markup language and used to enforce a property (such as “bold”) for text runs within regions defined by the elements. Thus properties such as encapsulation and inheritance can be applied.
The shape objects can be represented using a markup language, such as XML, to increase the transparency of the authored documents, increase the control of information, and to facilitate the transfer of data between dissimilar programs, such as between a word processing program and a spreadsheet program.
Additionally, a schema can be used to define and enforce rules for storing text runs within shape objects. The schema can be used by programs of differing types to ensure uniform handling of shared data. Likewise, the schema can be used to help recover from corrupted document files.
These and other features and advantages will be apparent from a reading of the following detailed description and a review of the associated drawings. It is to be understood that both the foregoing general description and the following detailed description are explanatory only and are not restrictive. Among other things, the various embodiments described herein may be embodied as methods, devices, or a combination thereof. Likewise, the various embodiments may take the form of an entirely hardware embodiment, an entirely software embodiment or an embodiment combining software and hardware aspects. Furthermore, various operating systems and applications can be used to provide a system providing thematic graphical objects. The disclosure herein is, therefore, not to be taken in a limiting sense.
Non-limiting and non-exhaustive embodiments are described with reference to the following figures, wherein like reference numerals refer to like parts throughout the various views unless otherwise specified.
a-2c are block diagrams illustrating a document relationship hierarchy for various modular parts utilized in a file format for representing a word processor document according to various illustrative embodiments.
As briefly described above, embodiments are directed to providing common document themes for graphic objects whereby documents authored by different types of applications can have a relatively uniform appearance. When reading the discussion of the routines presented herein, it should be appreciated that the logical operations of various embodiments are implemented (1) as a sequence of computer implemented acts or program modules running on a computing system and/or (2) as interconnected machine logic circuits or circuit modules within the computing system. The implementation is a matter of choice dependent on the performance requirements of the computing system. Accordingly, the logical operations illustrated and making up the embodiments of the described herein are referred to variously as operations, structural devices, acts or modules. These operations, structural devices, acts and modules may be implemented in software, in firmware, in special purpose digital logic, and any combination thereof.
Referring now to the drawings, in which like numerals represent like elements, various aspects will be described. In particular,
Generally, program modules include routines, programs, components, data structures, and other types of structures that perform particular tasks or implement particular abstract data types. Other computer system configurations may also be used, including handheld devices, multiprocessor systems, microprocessor-based or programmable consumer electronics, minicomputers, mainframe computers, and the like. Distributed computing environments may also be used where tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules may be located in both local and remote memory storage devices.

The mass storage device 14 is connected to the CPU 5 through a mass storage controller (not shown) connected to the bus 12. The mass storage device 14 and its associated computer-readable media provide non-volatile storage for the computer 2. Although the description of computer-readable media contained herein refers to a mass storage device, such as a hard disk or CD-ROM drive, it should be appreciated by those skilled in the art that computer-readable media can be any available media that can be accessed by the computer 2.
By way of example, and not limitation, computer-readable media may comprise computer storage media and communication media. Computer storage media includes volatile and non-volatile, removable and non-removable media implemented in any method or technology for storage of information such as computer-readable instructions, data structures, program modules or other data. Computer storage media includes, but is not limited to, RAM, ROM, EPROM, EEPROM, flash memory or other solid state memory technology, CD-ROM, digital versatile disks (“DVJS’), or other optical storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or any other medium which can be used to store the desired information and which can be accessed by the computer 2.
According to various embodiments, the computer may operate in a networked environment using logical connections to remote computers through a network 18, such as the Internet. The computer 2 may connect to the network 18 through a network interface unit 20 connected to the bus 12. It should be appreciated that the network interface unit 20 may also be utilized to connect to other types of networks and remote computer systems. The computer 2 may also include an input/output controller 22 for receiving and processing input from a number of other devices, including a keyboard, mouse, or electronic stylus (not shown in
As mentioned briefly above, a number of program modules and data files may be stored in the mass storage device 14 and RAM 9 of the computer 2, including an operating system 16 suitable for controlling the operation of a networked personal computer. The mass storage device 14 and RAM 9 may also store one or more program modules. In particular, the mass storage device 14 and the RAM 9 may store a word processing application program 10. The word processing application program 10 is operative to provide functionality for the creation and structure of a word processor document, such as a document 27, in an open file format 24, such as an XML file format and/or a binary file format. According to one embodiment, the word processing application program 10 and other application programs 26 comprise a suite of application programs including word processor, spreadsheet, and slide presentation authoring application programs. As discussed in greater detail below, the format of shape object 28 can be understood, displayed, and modified by programs in the application suite.
Embodiments greatly simplify and clarify the organization of document features and data. The word processing program 10 organizes the ‘parts’ of a document (features, data, themes, styles, objects, and the like) into logical, separate pieces, and then expresses relationships among the separate parts. These relationships, and the logical separation of ‘parts’ of a document, make up a new file organization that can be easily accessed, such as by a developer's code. It should be understood that the following description is made in terms of a word processing program 10 and associated documents, but that embodiments are equally applicable to other applications and associated documents, for example, spreadsheet applications and documents, slide presentation applications and documents, and the like.

The various modular parts or components of the presentation (for use by a word processor, for example) hierarchy 208 are logically separate but are associated by one or more relationships. Each modular part is also associated with a relationship type and is capable of being interrogated separately and understood with or without the word processing application program 10 and/or with or without other modular parts being interrogated and/or understood. Thus, for example, it is easier to locate the contents of a document because instead of searching through all the binary records for document information, code can be written to easily inspect the relationships in a document and find the document parts effectively ignoring the other features and data in the file format 24. Thus, the code is written to step through the document in a much simpler fashion than previous interrogation code. Therefore, an action such as removing all the images, while tedious in the past, is now less complicated.
A modular content framework may include a file format container 207 associated with the modular parts. The modular parts include the document part 202 operative as a guide for properties of the document. The document hierarchy 208 may also include a document properties part 205 containing built-in properties associated with the file format 24, and a thumbnail part 209 containing a thumbnail associated with the file format 24. It should be appreciated that each modular part is capable of being extracted from or copied from the document and reused in a different document along with associated modular parts identified by traversing relationships of the modular part reused. Associated modular parts are identified when the word processing application 10 traverses inbound and outbound relationships of the modular part reused.
Aside from the use of relationships in tying parts together, there is also a single part in every file that describes the content types for each modular part. This gives a predictable place to query to find out what type of content is inside the file. While the relationship type describes how the parent part will use the target part (such as “image” or “stylesheet”), the content or part type 203 describes what the actual modular part is (such as “JPEG” or “XML”) regarding content format. This assists both with finding content that is understood, as well as making it easier to quickly remove content that could be considered unwanted (for security reasons, etc.). The key to this is that the word processing application must enforce that the declared content types are indeed correct. If the declared content types are not correct and do not match the actual content type or format of the modular part, the word processing application should fail to open the modular part or file. Otherwise potentially malicious content could be opened.

Other modular parts include a footer part 227 containing footer data associated with the document, a header part 229 containing header data associated with the document and a bibliography part 231 containing bibliography data and/or underlying data of a bibliography associated with the document. Still further, the modular parts may include a spreadsheet part 249 containing data defining a spreadsheet object associated with the document, an embedded object part 251 containing an object associated with the document, and a font part 253 containing data defining a font associated with the document.
Referring to
Other modular parts may also include an embedded object part 253 containing an object associated with the document, a second user data part 245 containing customized data capable of being read into the file format container and changed. As an example, embodiments make it easier for a programmer/developer to locate an embedded object in a document because any embedded object has an embedded object part 253 separate in the file format 24 with corresponding relationships expressed. The embedded object part 253 as are other modular parts, is logically broken-out and separate from other features & data of the document. It should be appreciated that modular parts that are shared in more than one relationship are typically only written to memory once. It should also be appreciated that certain modular parts are global and thus, can be used anywhere in the file format. In contrast, some modular parts are non-global and thus, can only be shared on a limited basis.
In various embodiments, the file format 24 may be formatted according to extensible markup language (“XML”) and/or a binary format. As is understood by those skilled in the art, XML is a standard format for communicating data. In the XML data format, a schema is used to provide XML data with a set of grammatical and data type rules governing the types and structure of data that may be communicated. The XML data format is well-known to those skilled in the art, and therefore not discussed in further detail herein. The XML formatting closely reflects the internal memory structure. Thus, an increase in load and save speed is evident.
Embodiments allow documents to be more programmatically accessible. This enables a significant number of new uses that are simply too hard for previous file formats to accomplish. For example, a server-side program is able to create a document for someone based on their input, or to create a report on Company A for the time period of Jan. 1, 2004-Dec. 31, 2004.
a-2c also include relationship types utilized in the file format 24 according to various illustrative embodiments. The relationship types associated with the modular parts not only identify an association or dependency but also identify the basis of the dependency. The relationship types include the following: a code file relationship capable of identifying potentially harmful code files, a user data relationship, a hyperlink relationship, a comments relationship, an embedded object relationship, a drawing object relationship, an image relationship, a mail envelope relationship, a document properties relationship, a thumbnail relationship, a glossary relationship, a chunk relationship, a stylesheet/theme relationship, and a spreadsheet relationship.

At operation 310, the word processing application 10 establishes relationships between newly written and previously written modular parts. The routine 300 then terminates at the return operation.
Referring now to
When at detect operation 404, the data examined has been written to a modular part, the routine 400 continues from detect operation 404 to detect operation 407. At detect operation 407 a determination is made as to whether all the data has been examined. If all the data has been examined, the routine 400 returns control to other operations at return operation 412. When there is still more data to examine, the routine 400 continues from detect operation 407 to operation 410 where the word processing application 10 points to other data. The routine 400 then returns to operation 402 described above.

Properties can be associated with text runs, individual characters or even other properties, and can be shared and overridden in a hierarchical manner (as discussed briefly above). For example, an application can create a paragraph style (which can be a default collection of properties) that is to be applied to all paragraphs a document. By defining such a style in a single location, it becomes much easier to enforce consistent formatting across a document. Thus, the process for altering the entire look of a document is greatly simplified: desired changes can be made in one location so that the rest of the document automatically reflects the changes.
To provide further flexibility, properties can be overridden locally. When it is desired that a particular paragraph in a document should deviate from a default paragraph style, the specific properties can be specified locally to create an override situation for any (undesired) specified properties. A process (such as a translator, a renderer, a printer, and the like) can resolve both the locally and globally defined properties, with the locally defined properties typically taking precedence over the globally defined properties.
In various embodiments, a user interface (Ul) can be provided for defining (including editing) and/or selecting the shape object. The UI can be used to define text elements such as colors, fonts, and formatting of text runs that are included in the shape object. For example, the shape object can have foreground and background colors. Text can automatically be inset or sized to appropriately fill the shape object such that the entire text run is visible when displaying the shape object.
Additionally, text within the shape object can be controlled through parent objects that encapsulate the (child) shape object. Properties such as color and style can be used to override settings of child objects such that the objects can have a common appearance. For example, bullets (or other formatting) for an outline can be specified at a high level, so that the formatting overrides properties (if any similarly defined properties exist) of the child objects.
Shape objects can also be used to hold content (such as graphics and text runs). The content can then be displayed in documents that access the shape object. When cutting and pasting content (from the shape object or otherwise) displayed in a document, information from any shape object parent objects (or, for example, a pointer to the theme object) can be placed on the clipboard.
