Non-limiting and non-exhaustive embodiments of the present invention are described with reference to the following drawings. In the drawings, like reference numerals refer to like parts throughout the various figures unless otherwise specified.
The invention now will be described more fully hereinafter with reference to the accompanying drawings, which form a part hereof, and which show, by way of illustration, specific exemplary embodiments by which the invention may be practiced. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Among other things, the invention may be implemented in different embodiments as methods, processes, processor readable mediums, systems, business methods, or devices. Accordingly, the present invention may take the form of an entirely hardware embodiment, an entirely software embodiment or an embodiment combining software and hardware aspects. The following detailed description is, therefore, not to be taken in a limiting sense.
The invention is generally directed to providing automated assistance in managing rules and/or guidelines regarding the usage of branded content for a project, e.g., an advertising campaign, event, signage, decoration, presentation, and the like. Initially, one or more queries regarding the project are presented to the user. Based on the user's responses to the queries, other queries may be presented until branded content that is approved for the project's intended use(s) is automatically identified and made available to the user. The determination of which content to provide to a user is based at least in part on rules and/or guidelines regarding a brand that can be relatively static or dynamically updated.
Generally, as used in this application, a brand is a representation of a level of quality, value, and/or association with a specific known source of goods/services, e.g., an organization, individual, line of products/services. The brand can be embodied in different forms of electronic content, which can include media objects that can be communicated electronically over a network and/or included in a processor readable media. Also, a brand's “value” is typically reflected in how the product/service, and/or organization/individual, is perceived by their target audience or the marketplace generally. Different meanings and therefore different values can be associated with different audiences. Furthermore, the meaning and the value of the brand for each audience is typically employed to develop rules and guidelines for marketing products and/or services to each target audience. Additionally, the value of a brand for a web-based company may have a heightened importance due at least in part to the somewhat intangible nature of providing goods and/or services over a network vis-à-vis a brick and mortar facility.
Rules and/or guidelines for a brand are employed to evaluate the uses for a media object. These rules and/or guidelines can be employed to generate a logical decision tree of queries, which are displayed to the user. Based on the user's response to these queries, a media object can be subsequently provided to the user for use in a particular project. In yet at least another embodiment, a template of exemplary rules and guidelines can be provided for a new user that has not provided any. Based in part on a user's responses to a template of general queries, at least basic usage rules and guidelines for media objects can be generated for the new user.
In still another embodiment, the rules/guidelines can employ the format/type of a file and/or an application provided for a user's project to identify one or more media objects for a particular use. For example, if a user indicated a particular presentation file format for a project, those media objects suitable for use/display with the corresponding presentation application would be provided for consideration by the user. Further, other media objects unsuitable for use with the provided presentation file format wouldn't be provided, but might be presented as available for use if a different type of presentation application could be employed for that particular project.
Additionally, in at least one embodiment, if a brand rule and/or guideline regarding the use of a media object changes, the availability of that object for intended and/or actual use can be dynamically updated. For example, the availability of a media object for use in a presentation application can be dynamically updated based on a new change to a rule/guideline regarding its usage with a presentation. Also, each change to a rule and/or guideline for use with a brand can be dynamically updated in a database that is linked to an index of the media objects.
In at least one other embodiment, different types of rules and/or guidelines may be provided that can consider one or more factors of a user's project, including, but not limited to, geographic location, venue, target audience, price, duration, season, event, holiday, special occasion, type of media object requested, type of project, and the like. In one embodiment, these factors are provided by the user in response to one or more queries, and in other embodiments, these factors can be stored in a profile associated with, or selected by, the user.
A media object is an electronic form of content whose use with a brand can be controlled by rules and/or guidelines. Media objects can include, but are not limited to, alpha-numeric text, symbols, images, pictures, illustrations, graphics, fonts, characters, cartoons, video, color, service marks, trademarks, trade dress, audio recordings, drawings, presentations, advertisements, and the like. Additionally, a media object includes a unique identifier. In at least one embodiment, the unique identifier can be configured as metadata that can be arranged in one or more configurations, including but not limited to, XMP, EXIF, and IPTC. This metadata can include time and date information, geographic limitations, type(s) of approved uses such as an advertising campaign, and the like. Moreover, the unique identifier and/or the metadata can be employed to automatically map a media object to brand usage rules and/or guidelines.
Also, in at least one embodiment, the unique identifier for a media object can be configured as an object such as a smart object, digital object identifier (DOI), and/or a handle. This unique identifier may be included in a header of a file and/or injected into the actual data that characterizes the media object. One or more methods may be employed to inject a unique identifier into content contained in a media object's file, including, but not limited to, steganography, watermarking, and hard coding.
In one embodiment, a Handle System is employed to handle the unique identifiers for media objects. The Handle System provides a resolution service for media objects over a network, such as the Internet. The arrangement of the Handle System is somewhat similar to a Domain Name System (DNS), except that it is tailored for resolving unique identifiers of media objects instead of uniform resource locators (URLs) for websites. There are several Requests For Comment (RFCs) that explain the specific details of the Handle System, including RFC3650, 3651, and 3652. Additionally, the Handle System can be used to locate repositories that contain media objects given their unique handles. Other features of the Handle System include: (1) open, relatively well-defined protocol and data model; (2) infrastructure for application domains, e.g., images, music, digital libraries; (3) interoperability between many different information systems; and (4) a DNS can operate on the Handle System.
Additionally, if a unique identifier is configured with a media object as a DOI, handle, and/or smart object, it can provide at least some functionality, e.g., (1) addressing and resolvability over a network via a resolution system; (2) include a payload that conforms to a metadata description; (3) address that can be specified by a particular syntax; (4) invoke a method; and/or (5) universal operability.
In one or more embodiments, the invention can be implemented as an application or applet, which is separate from and/or a plug-in for another application such as an editor, word processor, DAM, presentation application, spreadsheet application, and the like. The invention can be arranged in different environments, including, but not limited to, host, peer to peer, client-server, and the like. One or more of these environments could also include a web server that provides access to information and media objects over a network by at least a browser application. In at least one embodiment, the rules/guidelines can be expressed in a database where newly received and previously received media objects can be indexed. Additionally, in at least one embodiment, the rules and/or guidelines for a brand can be managed in a virtual style book that controls at least some of the usage of media objects with the brand.

Referring now to TABLE II, if the following answers are received
Q1:ONLINE=YES, Q2:HEADER=NO, Q3:BACKGROUND=WHITE,
Q6:ORIENTATION=HORIZONTAL
then the appropriate logos may be determined from TABLE II to be L1, L4, L9 and L12. Similarly, if the following answers are received,
Q1:ONLINE=NO, Q3:BACKGROUND=BLACK, Q4:TIME_FRAME=LONG,
Q5:PERMANENT=YES, Q6:ORIENTATION=VERTICAL
then the appropriate logo may be determined from TABLE II to be L15.
It is understood that media objects, such as logos may be assigned priorities. For example, Table III herein below provides sample priorities assigned to logos L1-L16 from Table II.
Thus if logos L1, L4, L9 and L12 are provided to a user by an embodiment of the invention, then L1 and L9 would have higher priorities than L4 and L12.
Although the embodiment described above relates to logos, different embodiments of the invention can be used with a plurality of types of media objects. Thus, different embodiments can be used inter alia to provide brand media objects for signage, brochures, and other marketing and/or sales materials. Furthermore, different embodiments can be employed in different types of marketing campaigns, e.g., direct mail, in store promotions, banners, television, printed publications, e-mail, pay for click search, and advertisements on website landing pages.

Q4. How much time would you like for the presentation? (10 minutes, 15 minutes, 20 minutes, 40 minutes)
Q5. Will you be projecting the presentation on a screen, or distributing it in printed form?
Similarly, the invention can be used to locate an appropriate variable data template, vis a vis questions such as:
Q1. Is this a consumer or business advertisement?
Q2. Is this a particular campaign or a brand project?
Q3. In which publication will the advertisement be run?
Q4. What is the size of the advertisement?
Q5. Is the advertisement black & white, or color?
At least one embodiment of the invention can be used to determine and provide the user with different types of media objects for a particular use that are digital representations of images, sounds, and/or videos. For example, a user searching for an image for a presentation may be provided with questions such as:
Q1. What brand is this for?
Q2. What product line are you looking for?
Q3. Do you need a hero shot or a lifestyle shot?
Q4. Do you need a large or a small image?
Thus, it may be appreciated that one or more embodiments can provide one or more types of media objects that are determined to be appropriate for the usage(s) provided by the user in response to at least one query, file type, application, and the like.
The operation of certain aspects of the embodiments of the invention are now described with respect to
