In terms of provenance use, the scenario requires different sophisticated functions and it is not clear how existing technologies would implement them. So, the different parties must be able to understand the technical processes at different levels of granularity, resolve apparent conflicts in what appears to be expressed in the provenance data, obtain indications and evidence from the parts of the data set that can be based on, determine whether the provenance shows that the engineering process corresponds to a contract, verify whether two allegedly independent assessments are based on the same source, possibly defective, etc. To encourage the massive introduction of provenance technologies, it is necessary to understand how this type of function can be achieved through standardized guidelines and approaches. Overall, there is a gap in practice: provenance technologies are simply not used for the purpose described above. Even with encouragement, the current state of the art does not make it an easy task to reach the scenario due to the lack of standards, guidelines and tools. In particular, we can consider the gaps in content, management and usage, as modeled above. They are particularly suited to complex procurement agreements, outsourcing, strategic alliances, joint ventures, franchises, public-private partnerships, major construction projects and collective agreements. Oral agreements are based on the good faith of all parties and can be difficult to prove. Here, we identify the anchor/entry points that allow people outside the source group to represent their origin needs in the general aspects of the scenarios. The following diagrams illustrate the needs of the scenario from different angles. As an advisor to resolve the situation between the Petersons and Danny Davidson would require the negotiation of a new contract to purchase the house. In addition, the creation of a new legal contract, valid and applicable, will provide proof of an existing agreement in the future.
Conclusion Aspects of oral and oral treaties are not always recognized or applicable, even if the essential elements are visible. Nevertheless, the conclusion of an oral contract should indicate that the terms of the agreements, as well as the signatures of the parties concerned, provide visible evidence of an existing contract.
