If I'm building a new application that uses DOIs, how does DOI resolution work, what's the relationship between the DOI and Handle Systems, and what are the key design considerations for my application? Provide a concise overview based on the factsheets.
Navigate to the 'Resources' page. Click on the 'DOI Resolution Documentation' factsheet and extract information about the DOI resolution process. Return to the 'Resources' page. Click on the 'DOI System and the Handle System' factsheet and extract information about the relationship between the DOI System and the Handle System. Return to the 'Resources' page. Click on the 'Designing DOI Applications' factsheet, scroll to view all key design considerations, and extract them. Synthesize the gathered information to answer the proposed task.
Describe the core mechanism of DOI resolution, mentioning the DOI Proxy Server and its interaction with the Handle System. Explain the relationship between the DOI System and the Handle System, explicitly stating that the Handle System is the underlying infrastructure but the DOI System provides a broader framework (e.g., 'DOI names are more than handles'). List all five key design considerations for building DOI-enabled applications: 'What are we identifying with this identifier?', 'What are we resolving to from this identifier?', 'What metadata are we associating with this DOI name?', 'What are the interoperability requirements?', and 'How will the DOI application be paid for?'. Synthesize the information from the three factsheets into a concise answer that directly addresses the user's questions about implementing DOI functionality.
