 To render citations and bibliographies, CSL processors not only require CSL style and locale files, but also bibliographic metadata.

-### Mendeley CSL-JSON
-
-Mendeley provided the following documentation on their use of CSL-JSON:
-
-Support for the CSL Embedded Citation Object format is available in Mendeley Desktop 1.0 and later.
-
-The CSL citation data object consists of:
-
-* a required "schema" element of type "string", set to the URI of the schema
-* a required "citationID" element of type "string" or "number", set to ???
-* a "citationItems" element of type "array", containing "objects" with the data of the individual cites.
-  The individual cite object are structured as:
-  + a required "id" element of type "string" or "number", set to an unique cite ID
-  + a "itemData" element of type "object", described in `csl-data.json/#/items` , 
-    containing the metadata of a single bibliographic item
-    (this object is returned in citeproc-js by `sys.retrieveItem()` )
-  + an "uris" element of type "array", which can contain any number of URIs (of type "string") to the bibliographic item
-  + a "prefix" element of type "string"
-  + a "suffix" element of type "string"
-  + a "locator" element of type "string"
-  + a "label" element of type "string", set to one of the CSL locator types (see <https://docs.citationstyles.org/en/1.0.1/specification.html#locators>)
-  + a "suppress-author" element of type "string", "boolean" or "number"
-  + a "author-only" element of type "string", "boolean" or "number"
-* a "properties" element of type "object" containing:
-  + a "noteIndex" element of type "number", set to the index of the footnote or endnote
-* (Mendeley-specific) a "mendeley" element of type "object" containing:
-  + a "previouslyFormattedCitation" element of type "string", 
-   set to the rendered output of the cite of the previous rendering round
-   (this can be used to determine if the user manually altered the output)
-  + a "manualFormatting" element of type "string",
-    set to the user-customized output of the cite (this output will be used in favor of the generated output)
-
-The method to embed metadata for citations and bibliographies typically varies between word processors.
-Currently Mendeley uses:
-
-* For Word for Windows:
-  in-text citations and bibliographies are represented by a field code of type `wdFieldAddin` or temporarily represented as a bookmark if exporting to OpenOffice.
-
-* For OpenOffice:
-  in-text citations are of type `com.sun.star.text.ReferenceMark`.
-  Bibliographies are of type `com.sun.star.text.TextSection` or temporarily represented as a bookmark if exporting to Word.
