UC-5.3 Prototyping
Summary
Number	UC-5.3
Name	Prototyping
Context	UC-5 Preservation Planning
Sub-Use Cases	None
Overview	Monitor Technology creates and tests prototypes and sends the results to Develop Preservation Strategies and Standards and Develop Packaging Designs and Migration Plans
Actors	Develop Packaging Designs and Migration Plans Develop Preservation Strategies and Standards Monitor Technology
Description
Preconditions	UC-1 Ingest
Trigger	Develop Preservation Strategies and Standards sends prototype requests to Monitor Technology (Step 9 of UC-5.4) or Develop Packaging Designs and Migration Plans sends [migration software] prototype request to Monitor Technology (Step 6 of UC-5.7)
Successful outcome	Monitor Technology sends prototype results to Develop Preservation Strategies and Standards and Develop Packaging Designs and Migration Plans
Steps	Monitor Technology receives prototype requests from Develop Preservation Strategies and Standards (OAIS Page 4-14) Monitor Technology receives prototype requests from Develop Packaging Designs and Migration Plans (OAIS Page 4-14) Monitor Technology creates and tests prototypes (OAIS Page 4-14) Monitor Technology sends prototype results to Develop Preservation Strategies and Standards (OAIS Page 4-14) Monitor Technology sends prototype results to Develop Packaging Designs and Migration Plans (OAIS Page 4-14)

Documentation
Citations	OAIS Page 4-14 section 4.1.1.6 "The Monitor Technology function is responsible for tracking emerging digital technologies, information standards and computing platforms (i.e., hardware and software) to identify technologies which could cause obsolescence in the archive's computing environment and prevent access to some of the archives current holdings. This function may contain a prototyping capability for better evaluation of emerging technologies and receive prototype requests from Develop Preservation Strategies and Standards and from Develop Package Designs and Migration Plans. This function sends reports, external data standards, prototype results and technology alerts to Develop Preservation Strategies and Standards. It also sends prototype results to Develop Package Designs and Migration Plans."

Notes
	According to the text, the function Develop Packaging Designs and Migration Plans is responsible for developing prototypes, and Monitor Technology may contain a prototyping capability. According to the diagram, Monitor Technology does this work. Consider dividing this use case into two cases: one for prototyping requests from Develop Packaging Design and Migration Plans, one for prototyping requests from Develop Preservation Strategies and Standards
