		+	# '''Generate AIP''' extracts Preservation Description Information (PDI) from SIP (OAIS Page 4-50)
		+	# '''Administrator''' adds or modifies PDI if necessary (OAIS Page 4-50)
		+	# '''Generate AIP''' receives archive standards and policies from '''Administration>Establish Standards and Policies''' (OAIS Page 4-11)
		+	# '''Generate AIP''' requests report from '''Data Management>Generate Report''' on additional information to be included in the AIP's descriptive information, and that is necessary to complete the AIP (OAIS Page 4-6)
		+	# '''Generate AIP''' receives report from '''Data Management>Generate Report''' (OAIS Figure F-1:Composite of Functional Entities Page F-2)
		+	# '''Generate AIP''' produces required descriptive information for AIP, based on requirements provided in the report received from '''Data Management>Generate Report''' (OAIS 4.1.1.2, page 4-6)
		+	#'''Generate AIP''' conducts format conversions, data representation conversions, and reorganization of SIP content as necessary, according to data formatting and documentation standards.(OAIS 4.1.1.2, page 4-6)
		+	# '''Generate AIP''' assembles AIP (OAIS Page 4-6)
		+	# '''Generate AIP''' provides AIP to '''Generate Descriptive Information''' (OAIS Figure 4-2:Functions of Ingest Page 4-5)
		+	# '''Generate AIP''' sends SIP or AIP to '''Administration>Audit Submission''' (OAIS Page 4-6)
		+	# '''Generate AIP''' receives SIP or AIP audit report from '''Administration>Audit Submission''' (OAIS Page 4-11, 4-12)

		+	Page 4-6, Section 4.1.1.2: "The '''Generate AIP''' function transforms one or more SIPs into one or more AIPs that conform to the archive’s data formatting and documentation standards. This may involve file format conversions, data representation conversions or reorganization of the content information in the SIPs. The Generate AIP function may issue report requests to Data Management to obtain reports of information needed by the Generate AIP function to produce the Descriptive Information that completes the AIP. This function sends SIPs or AIPs for audit to the Audit Submission function in Administration, and receives back an audit report."
		+
		+	Page 4-11, 4-12, Section 4.1.1.5: "The Audit Submission function will verify that submissions (SIP or AIP) meet the specifications of the Submission Agreement.... An audit report is provided to Ingest. After the audit process is completed, any liens are reported to the Producer, who will then resubmit the SIP to Ingest or appeal the decision to Administration. After the audit is completed, a final ingest report is prepared and provided to the Producer and to Negotiate Submission Agreement."
		+
		+	Page 4-11, Section 4.1.1.5: "Based on these inputs, archive standards and policies are established and sent to other Administration functions and the other Functional Entities for implementation. The standards include format standards, documentation standards and the procedures to be followed during the Ingest process."
		+
		+	Page 4-50, Section 4.3.2: "The simplest form of the process involves removing the Content Information, PDI and Package Descriptors from the Producer transfer media and queuing them for storage by the Archival Storage and Data Management functional entities. In more complex cases, the PDI and Package Descriptors may have to be extracted from the Content Information or input by OAIS personnel during the ingest function; the encoding of the information objects or their allocation to files may have to be changed."

		+	*It is not clear what infomation is being requested from '''Data Management>Generate Report'''. OAIS s 4.1.1.2 (p 4-6) states "The Generate AIP function may issue report requests to Data Management to obtain reports of information needed by the Generate AIP function to produce the Descriptive Information that completes the AIP." This seems to suggest that ''Generate Report'' is providing information about how to assemble the AIP (such as requirements for the PDI and packaging information). These would be provided to the Data Management Database by ''Establish Policies and Standards''.
		+	**Not true. On further reading, it seems that the information in the report is supplemental descriptive information that already exists in the Data Management database, that is needed to complete the descriptive information required by the AIP. Step
		+	*Step 2 and Step 3 are inferred from text on page 4-50. The OAIS does not explicitly state that content and PDI extraction takes place as part of the Generate AIP activity.
