1. The document discusses the status of a system rewrite that will occur in two steps - first replacing the existing query system and then the deposit system. 2. It provides statistics on deposits and queries over time as well as system performance details. 3. The quality of metadata is assessed as generally weak for other purposes beyond linking, though link persistence is strong. Error reports from end users remain steady at around 3500 per month.

- 9. Quality Metadata is good enough for linking … generally weak for other purposes. Link persistence is strong, but could be better 5-10% of tested DOIs fail to reach original target (or result in an error) Error reports from end users remain steady ~3500 errors/month 20% get fixed by publishers (within 30 days) 20 notices/day to end users who reported the problem Coming in 2010: Quality audits initiated by CrossRef staff on targeted members 38,193,723 12,039,157 4,835,479 16,139,751 988,764 3,807,396 1,359,241 5,582,856 3,055,090 DOI Total Initial Only No First Name One Author No Article Title No Author No Page No Issue No Volume
