Patent Application
20090183108
Modern data processing systems, such as general purpose computer systems, allow the users of such systems to create a variety of different types of data files. For example, a typical user of a data processing system may create text files with a word processing program such as Microsoft Word or may create an image file with an image processing program such as Adobe's PhotoShop. Numerous other types of files are capable of being created or modified, edited, and otherwise used by one or more users for a typical data processing system. The large number of the different types of files that can be created or modified can present a challenge to a typical user who is seeking to find a particular file which has been created.
Modern data processing systems often include a file management system which allows a user to place files in various directories or subdirectories (e.g. folders) and allows a user to give the file a name. Further, these file management systems often allow a user to find a file by searching for the file's name, or the date of creation, or the date of modification, or the type of file. An example of such a file management system is the Finder program which operates on Macintosh computers from Apple Computer, Inc. of Cupertino, Calif. Another example of a file management system program is the Windows Explorer program which operates on the Windows operating system from Microsoft Corporation of Redmond, Wash. Both the Finder program and the Windows Explorer program include a find command which allows a user to search for files by various criteria including a file name or a date of creation or a date of modification or the type of file. However, this search capability searches through information which is the same for each file, regardless of the type of file. Thus, for example, the searchable data for a Microsoft Word file is the same as the searchable data for an Adobe PhotoShop file, and this data typically includes the file name, the type of file, the date of creation, the date of last modification, the size of the file and certain other parameters which may be maintained for the file by the file management system.
Certain presently existing application programs allow a user to maintain data about a particular file. This data about a particular file may be considered metadata because it is data about other data. This metadata for a particular file may include information about the author of a file, a summary of the document, and various other types of information. A program such as Microsoft Word may automatically create some of this data when a user creates a file and the user may add additional data or edit the data by selecting the “property sheet” from a menu selection in Microsoft Word. The property sheets in Microsoft Word allow a user to create metadata for a particular file or document. However, in existing systems, a user is not able to search for metadata across a variety of different applications using one search request from the user. Furthermore, existing systems can perform one search for data files, but this search does not also include searching through metadata for those files.
Methods for managing data in a data processing system and systems for managing data are described herein.
A method of managing data in one exemplary embodiment includes capturing metadata from a plurality of files created by a plurality of different software applications which execute on a data processing system. The type of information in the metadata for the files of a first software application differs from the type of information in metadata for files of a second software application. This captured metadata may be searched. In one embodiment, this search may occur concurrently for all of the metadata from the different files created by or used by the different software applications. In one implementation of this method, a single search interface may be provided to search all of the metadata for all of the different files created by the different software applications, thereby allowing a single search to search through all of the metadata for all of the files created by the different software applications. Further, the single search may also search through non-metadata such as the indexed (or non-indexed) content of the actual data files.
According to another aspect of the invention, an exemplary method includes capturing metadata from a plurality of different files created by a plurality of different software applications and storing the metadata on a storage medium in a flat file format. Another aspect relates to a flat file format for the metadata on the storage medium.
Another aspect of the present invention relates to various user interfaces which may be provided by a system to allow a user to search through the metadata. In one exemplary embodiment of such a user interface, the method includes capturing metadata from a plurality of files created by a plurality of different software applications and displaying a search input interface for searching through the metadata, wherein the type of information in metadata for files of a first software application differs from the type of information in metadata for files of a second software application. Various implementations of user interfaces are discussed for search input and also for the presentation (e.g. display) of search results. For example, the search results may be displayed in multiple different formats (e.g. list view, icon view, column view) and they may be displayed with headers or titles which separate the groups of matches in a search results list. Further, the displayed results may be limited to a predetermined number (or a dynamically generated number) for each category so that a limited viewing can still display multiple categories within a search result window. Further, a search query can be saved as a folder which appears within a user configurable portion of the search results window, and a selection of the folder causes another search to be performed using the saved search query (sometimes also referred to as search criteria). A display of the search results from the saved search query can then be sorted or further searched to limit the results to a subset of the original matches from the saved search query. Numerous other user interface implementations are shown and described. Another user interface feature includes the ability to provide both a list view and another view (e.g. icon view) for different portions (e.g. different categories) of a search results window.
Another aspect of the present invention relates to a software architecture for managing metadata. One exemplary embodiment of this architecture includes a first plurality of application programs which are capable of creating a plurality of different data files and a metadata management program which is coupled through programming interfaces with the first plurality of application programs and which is coupled to a file system storage of metadata which is captured from files created by the first plurality of application programs. Normally, the type of information in metadata for files of a first application program differs from the type of information in metadata for files of a second application program. The metadata management program is also coupled to other (non-metadata) sources of information about the data files such as an indexed database of the full text content of the data files and software which is capable of searching this indexed database. Search queries which are directed to the metadata may also be concurrently directed to the non-metadata sources so that the search results include matches from both the metadata and the non-metadata sources, and these searches, through both metadata and non-metadata sources, may be in response to a single search query or a single search request or command and these searches may be performed concurrently.
Another aspect of the inventions described herein relates to one or more importers which interact with new or modified files created by different application programs. These one or more importers may be invoked (e.g. called) by the application programs or by an operating system component (e.g. a metadata processing software) which responds to a call from the application programs or from an operating system kernel. In one particular example, an importer is called by a metadata processing software in response to a notification from an OS kernel that a new file has been created or an existing file has been modified; in this case, the particular importer called by the metadata processing system will typically depend upon the type of file (e.g. text file or image file or MP3 file, etc.), although one, single importer for all file types on a system may be used regardless of the type of file. An importer will typically specify a file path name for the extracted metadata and specify selected data to be extracted and written into the file path name of the file containing the extracted metadata.
Another aspect of the inventions described herein relates to performing a search through a system while receiving input from a user, where the search is through a plurality of data files created by different software applications on a data processing system. In an exemplary method of this aspect, the data processing system begins a search through the plurality of data files as the user enters input and before the user completes the entry of the search query. Thus, a user may enter a search (“quick brown fox”) and before the user has entered “fox,” the data processing system has searched through, or begins to search through, the plurality of data files created by different software applications and has displayed the list of matches to the partial search query “quick brown” (or at least begins to display a partial list of matches to the partial search query “quick brown”). This search may be performed through the plurality of data files as well as the metadata for the plurality of data files, wherein the type of information in metadata for files of a first software application differs from the type of information in metadata for files of a second software application. The search results may be sorted by relevancy, and the system may display first only a partial list of matches and then, in response to a user request, display all the matches. The search results may be organized by categories (e.g. see
Another aspect of the inventions relates to a method of selecting a group of items, such as a group of individual data files. In an exemplary method of this aspect, a data processing system receives a selection of a plurality of items such as data files, folders (e.g. graphical user interface representations of subdirectories), application programs or a combination of one or more of these items. This selection may be performed by one of the many conventional ways to select a plurality of items such as (a) pointing a cursor at each item individually (e.g. through movement of a mouse) and indicating a selection individually by, for example, pressing and releasing a button such as a mouse's button; (b) pointing a cursor at a first item in a list and indicating a selection of the first item and pointing the cursor at a last item in a list of items and indicating a selection of all items from the first item to the last item in the list; (c) drawing a selection rectangle by a dragging operation of the cursor, etc. After the selection of the plurality of items has been received, the data processing system receives a command to create a new folder and add or move, e.g. in one operation, the selected plurality of items into the new folder. The add operation creates the new folder (optionally with a name specified by the user as a result of a prompt or request by the system) and copies the selected files into the new folder, which represents a new subdirectory. This add operation is in response to the single command which requests that a new folder be created and that copies of the selected items be created and stored with a path name reflecting storage within the new folder. The move operation also creates a new folder (optionally with a name specified by the user as a result of a prompt or request by the system) and may merely change the path names associated with each of the selected items, which changed path names reflect the new file system location (within the subdirectory of the new folder) of the selected items.
Other aspects of the present invention include various data processing systems which perform these methods and machine readable media which perform various methods described herein.

As shown in
It will be apparent from this description that aspects of the present invention may be embodied, at least in part, in software. That is, the techniques may be carried out in a computer system or other data processing system in response to its processor, such as a microprocessor, executing sequences of instructions contained in a memory, such as ROM 107, RAM 105, mass storage 106 or a remote storage device. In various embodiments, hardwired circuitry may be used in combination with software instructions to implement the present invention. Thus, the techniques are not limited to any specific combination of hardware circuitry and software nor to any particular source for the instructions executed by the data processing system. In addition, throughout this description, various functions and operations are described as being performed by or caused by software code to simplify description. However, those skilled in the art will recognize what is meant by such expressions is that the functions result from execution of the code by a processor, such as the microprocessor 103.
The method of
The method of
One particular field which may be useful in the various metadata formats would be a field which includes an identifier of a plug in or other software element which may be used to capture metadata from a data file and/or export metadata back to the creator application.
Various different software architectures may be used to implement the functions and operations described herein. The following discussion provides one example of such an architecture, but it will be understood that alternative architectures may also be employed to achieve the same or similar results. The software architecture shown in
The software architecture 400 also includes a file system directory 417 for the metadata. This file system directory keeps track of the relationship between the data files and their metadata and keeps track of the location of the metadata object (e.g. a metadata file which corresponds to the data file from which it was extracted) created by each importer. In one exemplary embodiment, the metadata database is maintained as a flat file format as described below, and the file system directory 417 maintains this flat file format. One advantage of a flat file format is that the data is laid out on a storage device as a string of data without references between fields from one metadata file (corresponding to a particular data file) to another metadata file (corresponding to another data file). This arrangement of data will often result in faster retrieval of information from the metadata database 415.
The software architecture 400 of
The method of
It will be appreciated that the notification, if done through the OS kernel, is a global, system wide notification process such that changes to any file will cause a notification to be sent to the metadata processing software. It will also be appreciated that in alternative embodiments, each application program may itself generate the necessary metadata and provide the metadata directly to a metadata database without the requirement of a notification from an operating system kernel or from the intervention of importers, such as the importers 413. Alternatively, rather than using OS kernel notifications, an embodiment may use software calls from each application to a metadata processing software which receives these calls and then imports the metadata from each file in response to the call.
As noted above, the metadata database 415 may be stored in a flat file format in order to improve the speed of retrieval of information in most circumstances. The flat file format may be considered to be a non-B tree, non-hash tree format in which data is not attempted to be organized but is rather stored as a stream of data. Each metadata object or metadata file will itself contain fields, such as the fields shown in the examples of
A flexible query language may be used to search the metadata database in the same way that such query languages are used to search other databases. The data within each metadata file may be packed or even compressed if desirable. As noted above, each metadata file, in certain embodiments, will include a persistent identifier which uniquely identifies its corresponding data file. This identifier remains the same even if the name of the file is changed or the file is modified. This allows for the persistent association between the particular data file and its metadata.
Various different examples of user interfaces for inputting search parameters and for displaying search results are provided herein. It will be understood that some features from certain embodiments may be mixed with other embodiments such that hybrid embodiments may result from these combinations. It will be appreciated that certain features may be removed from each of these embodiments and still provide adequate functionality in many instances.
The combination of text entry region 709 and the search parameter menu bar allow a user to specify a search query or search parameters. Each of the configurable pull down menus presents a user with a list of options to select from when the user activates the pull down menu. As shown in
It will also be appreciated that the various options in the pull down menus may depend upon the fields within a particular type of metadata file. For example, the selection of “images” to be searched may cause the various fields present in the metadata for an image type file to appear in one or more pull down menus, allowing the user to search within one or more of those fields for that particular type of file. Other fields which do not apply to “images” types of files may not appear in these menus in order reduce the complexity of the menus and to prevent user confusion.
Another feature of the present invention is shown in
The window 1001 includes an additional feature which may be very useful while analyzing a search result. A user may select individual files from within the display region 1005 and associate them together as one collection. Each file may be individually marked using a specific command (e.g. pressing the right button on a mouse and selecting a command from a menu which appears on the screen, which command may be “add selection to current group”) or similar such commands. By individually selecting such files or by selecting a group of files at once, the user may associate this group of files into a selected group or a “marked” group and this association may be used to perform a common action on all of the files in the group (e.g. print each file or view each file in a viewer window or move each file to a new or existing folder, etc.). A representation of this marked group appears as a folder in the user-configurable portion 1003A. An example of such a folder is the folder 1020 shown in the user-configurable portion 1003A. By selecting this folder (e.g. by positioning a cursor over the folder 1020 and pressing and releasing a mouse button or by pressing another button) the user, as a result of this selection, will cause the display within the display region 1005 of the files which have been grouped together or marked. Alternatively, a separate window may appear showing only the items which have been marked or grouped. This association or grouping may be merely temporary or it may be made permanent by retaining a list of all the files which have been grouped and by keeping a folder 1020 or other representations of the grouping within the user-configurable side bar, such as the side bar 1003A. Certain embodiments may allow multiple, different groupings to exist at the same time, and each of these groupings or associations may be merely temporary (e.g. they exist only while the search results window is displayed), or they may be made permanent by retaining a list of all the files which have been grouped within each separate group. It will be appreciated that the files within each group may have been created from different applications. As noted above, one of the groupings may be selected and then a user may select a command which performs a common action (e.g. print or view or move or delete) on all of the files within the selected group.
The window 1201 shown in
A column 1211 of window 1201 allows a user to select various search parameters by selecting one of the options which in turn causes the display of a submenu that corresponds to the selected option. In the case of
The window 1301 shown in
The search results user interface shown in
It will be appreciated that this method may employ various alternatives. For example, a window may appear after the command option 2232 or 2233 has been selected, and this window asks for a name for the new folder. This window may display a default name (e.g. “new folder”) in case the user does not enter a new name. Alternatively, the system may merely give the new folder or new storage facility a default path name. Also, the system may merely create the new folder and move or copy the items into the new folder without showing the new window as shown in
In the foregoing specification, the invention has been described with reference to specific exemplary embodiments thereof. It will be evident that various modifications may be made thereto without departing from the broader spirit and scope of the invention as set forth in the following claims. The specification and drawings are, accordingly, to be regarded in an illustrative sense rather than a restrictive sense.
