Abstract: Some embodiments described herein relate to a computer implemented method that includes performing a first work step associated with a first activity and with a first data product and performing a second work step associated with a second activity and associated with a second data product. A first chain of trust between the first work step and the second work step can be defined by defining a second manifest document that is associated with the second data product and that references a first manifest document associated with the first data product. An immutable data structure representing a second chain of trust independent of the first chain of trust can be defined by submitting the first manifest document and the second manifest document to a distributed ledger for validation.

Abstract: Some embodiments described herein relate to a computer implemented method that includes receiving a token that includes a reference to a first encrypted archive recorded in a distributed ledger. The first encrypted archive can be decrypted using the token to retrieve a first manifest document, which can be associated with a first activity of the complex transaction. The first manifest document can identify a second encrypted archive. The second encrypted archive can be decrypted using the token to retrieve a second manifest document, which can be associated with a second activity of the complex transaction. The second manifest document can include a reference to a data product, which can be retrieved. A continuity of the complex transaction between the second activity and the first activity can be verified based on the data product.

Abstract: A software agent is provided which executes instructions on a local user's computer to retrieve potentially changing information content from remote target sources, including web pages, over a computer network, such as the Internet. Different types of software agents are available to retrieve different types of information content from remote sites. Agent types include a smart agent, a search agent, a custom agent for detailed tasks and an RSS agent for retrieving structured XML format documents from remote Internet sites. Information retrieved by the agents is formatted and stored locally for presentation in a publication on the local computer. Publication templates can display target content retrieved by multiple agents from many different remote target pages.

Abstract: A system for reliably retrieving information which may be in any one of several possible formats and for subsequent display of that information in any one of several possible formats. User-defined agents are used to retrieve target data based on a heuristic algorithm and to store the target data in a canonical form, ready for republication in whatever form best suits a particular application. The system is particularly well suited to obtaining information over the internet for display on a desktop system, but it is also well suited for applications having only limited display or computational capabilities.
