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 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. The following are the minimal metadata for every paleoArchive in the network. Many records include additional desirable data and metadata; an ongoing extended metadata table is available here. To illustrate this standard more concretely, we use the dataset of \citet{Thornalley_2009} as an example (Figure 2 and Table below).  \begin{description}  \item[Base metadata] metadata that apply to the paleoArchive dataset  as a whole: \begin{description}  \item[dataSetName] name of the paleoArchive (record); dataset;  that is, an alphanumeric string that uniquely characterizes this record in the database, often based on site, authors, year and ancillary information \textit{example: RAPiD-12-1K.Thornalley.2009} \item[archiveType] \textit{example: marine sediments}  \item[investigator] \textit{example: David Thornalley}  \end{description}
