( Pages with a poll, Working Group )


Overview

In the Linked Earth context, a working group (WG) is a self-organized coalition of knowledgeable experts, whose activities are governed herewith. This page is dedicated to the discussion of data and metadata standards for historical documents, and aims to formulate a set of recommendations for such a standard.

Members of 'Historical Documents Working Group'

    This working group contains only the following member.

Sources

Data is usually compiled from different historical sources. The LiPD data structure supports several Publication, that is normally used for referring to the publication describing the data. So this data cluster can be used for historical sources as well, in addition to the current publication describing the data.


Scans, Pages

Each source can optionally have a bunch of images, that are the scans of the pages inside the source. Maybe this can be dropped for the LiPD format and only references to external images should be added to the quotes.

Quotes

Out of each sources, several quotes could be extracted by transcribing them. Related data would most probably go into "measurementTables".

  • Quote-ID: For later reference
  • Reference to source: maybe short form like "Author()Year" is adequate
  • Page: String of the page(s) number where the quote is extracted from
  • Scan: Optional link(s) to externally stored image of this page(s)
  • Language: The language of the quote (or it's translation)
  • Protolanguage: The language the quote was written originally
  • Quote: The quote itself (UTF8)
  • License: License of the quote (cc)
  • DOI: DOI, the quote is published

Events

Events, that are more like interpretations of the quote would go into "model part". Each events refers to

  • a quote
  • a position
  • a time

and contains a climate related data. (to be defined)

Position

The position different than for the other archive types is not fixed. Usually a compilation of several sources refer to different scattered locations. The location usually can be named but might covers different scales (continent, country, area, city, street,...) and terrain types (city, river, sea, ...). It best corresponds to the Geospatial metadata of LiPD; see also http://schema.org/Place .

Time

The time derived for an event from historical documents is usually more precise than for other archive types. Often the uncertainty is just days or even hours. So it would be best to code the absolute date by gregorian calendar and a string of type ISO 8601. Optionally an absolute gregorian year (may be with floating point fraction instead of integer) can be calculated as well.

  • Time
How should the event time primarily be defined:

The original sources often contain the information in calendar notation different than gregorian. Julian calendar was used in Europe in historical time, but outside Europe other calendars existed or still exist, likeweise in chinese or arabic documents.

Should the time optionally be coded in 'Other Calendar Systems':
