   abstract	= {In many disciplines, data are highly decentralized across
 		  thousands of online databases (repositories, registries,
 		  and knowledgebases). Wringing value from such databases
 		  depends on the discipline of data science and on the humble
 		  bricks and mortar that make integration possible;
 		  identifiers are a core component of this integration
 		  infrastructure. Drawing on our experience and on work by
 		  other groups, we outline 10 lessons we have learned about
 		  the identifier qualities and best practices that facilitate
 		  large-scale data integration. Specifically, we propose
 		  actions that identifier practitioners (database providers)
 		  should take in the design, provision and reuse of
 		  identifiers. We also outline the important considerations
 		  for those referencing identifiers in various circumstances,
 		  including by authors and data generators. While the
 		  importance and relevance of each lesson will vary by
 		  context, there is a need for increased awareness about how
 		  to avoid and manage common identifier problems, especially
 		  those related to persistence and
 		  web-accessibility/resolvability. We focus strongly on
 		  web-based identifiers in the life sciences; however, the
 		  principles are broadly relevant to other disciplines.},
