Patent 7,139,761 (the '761 patent) has been asserted by Leader Technologies, Inc. against Facebook, Inc. in a federal district court action alleging willful infringement. The '761 patent could pose a threat to numerous social network sites. This challenge is to determine whether the claims of the '761 patent are valid.
Summary / Description
| Summary / Description | Document properties are a compelling infrastructure on which to develop document management applications. A property-based approach avoids many of the problems of traditional heierarchical storage mechanisms, reflects document organizations meaningful to user tasks, provides a means to integrate the perspectives of multiple individuals and groups, and does this all within a uniform interaction framework. Document properties can reflect not only categorizations of documents and document use, but also expressions of desired system activity, such as sharing criteria, replication management, and versioning. Augmenting property-based document management systems with active properties that carry executable code enables the provision of document-based services on a property infrastructure. The combination of document properties as a uniform mechanism for document management, and active properties as a way of delivering document services, represents a new paradigm for document management infrastructures. The Placeless Documents system is an experimental prototype developed to explore this new paradigm. It is based on the seamless integration of user-specific, active properties. We present the fundamental design approach, explore the challenges and opportunities it presents, and show our architectures deals with them. |

Excerpt
Document properties are features of a document that are meaningful to users, rather than to the system. Documents can have any number of properties, reflecting the different features that might be relevant to users at different times or in different contexts. To emphasize the difference between interaction managed through document properties and the more traditional approach of interaction managed through document locations, we call our system Placeless Documents.
The Placeless Documents design is based on three core features: uniform interaction, user-specific properties, and active properties.
. . . .
Although a space is intended to manage documents across kernels autonomously, that does not imply that it receives no guidance from users. After all, a user is often better able to express needs and expected uses than a system is at guessing or extrapolating from current use. Expected patterns of use or current needs are, of course, simply properties of the document, and so can be expressed by attaching document properties.
