The flexible container described in section 2 can serialize any set of paleoenvironmental data with rich metadata. However this framework only becomes useful when a common vocabulary with explicit meanings is applied to the data. Developing this vocabulary requires buy-in from experts across the disparate domains of the paleogeosciences, and will be a gradual process of evolving standards. To begin this conversation, here we outline a preliminary metadata standards for required and extended metadata, based on phase 2 of the \href{ http://www.pages-igbp.org/workinggroups/2k-network/intro}{Past Global Changes (PAGES) past two thousand years (2k)} project.  \begin{description}  \item[base \item[Base  metadata] metadata that apply to the paleoArchive as a whole: \begin{description}  \item[paleoArchiveName] name of the paleoArchvive; \textit{example: RAPiD-12-1K.Thornalley.2009}  \item[archiveType] \textit{example: marine sediments}  \item[investigator] \textit{example: David Thornalley}  \end{description}  \item[Geospatial metadata] metadata that to the location of the study site:  \begin{description}  \item[latitude] both value (e.g., mean, max, min) and units; \textit{example: “value” : 62.08, “units” : decimalDegrees}  \item[longitude] both value (e.g., mean, max, min) and units; \textit{example: “value” : -17.82, “units” : decimalDegrees}  \item[siteName] \textit{RAPiD-12-1K}  \end{description}  \item[Publication metadata] metadata that to the publication(s) associated with the paleoArchive:  \begin{description}  \item[DOI] publication Digitial Object Identifier; \textit{example: 10.1038/nature07717}  \item[pubString] short text citation; \textit{example: Thornalley et al., 2009}  \end{description}  \item[paleoDataTable metadata] metadata associated with paleoDataTable:  \begin{description}  \item[paleoDataTableName] short name of the paleoData table; \textit{example: data}  \item[filename] measurement table filename (.csv); \textit{example: Atlantic0220Thornalley2009.csv}  \item[chronology] short name of chronology table used in this measurement table; \textit{example: chronology}  \end{description}  \end{description}  \end{description}
