Varia

… Chalcolithic occurs before Bell Beaker …

Introduction

For Leibnitz, “time” groups events that follow one another, while “space” groups objects that coexist.

Chronological turn

‘Monument druidique près de Gisors’ 1824

Stack of information layer in a GIS

In the 90’s, development of GIS in archaeology led to a “geographic turn” but no such a thing for the temporal dimension

Proposed framework

Workflow

• Asynchronous

• Distributed

• Project-based

Asynchronous, project-based and distributed work

Data papers

Building a framework to facilitate the publication of papers on temporal data alongside research papers

Very unprecise

Very precise

Help in publishing data papers to go FAIR

Platforms

Git, distributed version control system:

• GitHub https://github.com

• GitLab https://gitlab.com
  
  is the 🔝 popular web-platform for source code management and software development (with over 128 million public repositories)

Standardisation

• ISO
• CIDOC-CRM

Extended Date/Time Format (EDTF) Specification ISO 8601-2019 https://www.loc.gov/standards/datetime/

Use of CIDOC-CRM, promoting good practices

    A("-7XX/-509") --P170 defines time--> B("E52 Time-Span");

EDTF is an extension of the previously seen ISO-8601 Date format. It allows an accurate record of time events and durations whatever their fuzzyness (seasons, before, etc.)

Scripting Languages

• is the 1^st used worldwide and the 2^nd used by archaeologists.

• is a scripting language for data science, is the 1^st used by archaeologists but only the 18^th worldwide
