preserv-CM

Digital preservation of the main sources of the AddressForAll-Cameroonian database, maintained by the AddressForAll Institute.

To Cameroon was assigned: in the ISO 3166 context the geocode CM and the number 120; in Wikidata the identifier Q1009; in OpenStreetMap the relation id 192830.

Territorial organization

The national territory and its subdivisions represent jurisdictions:

• The country is divided into 10 regions (then-provinces), semi-autonomous, that are headed by a governor appointed by the president of the republic. The geocodes of the regions follow the convention registered by ISO 3166-2:CM. In OpenStreetMap it is agreed that the subdivision by regions corresponds to administrative level 4.

• The regions are subdivided into 58 departments that are headed by divisional officers (préfets) appointed by the president of the republic.

• The departments are subdivided into communes (arrondissements) that are headed by assistant divisional officers (sous-prefets).

• The communes are subdivided into districts that are headed by district heads (chefs de district).

The urban cadastres are found in the communes. [CONFIRM?]

The jurisdiction that assigns names to streets and the urban numbering system is the commune. [CONFIRM?]

Organization of this repository

In this git, only metadata is saved, that is, entity descriptors such as names and geocodes — maps and other data, stored externally because they are very large. The metadata was organized as follows, in the /data folder:

• /data: original input data, that is, metadata provided for the system.

  • jurisdictionLevel*.csv: jurisdictions (at all levels) and their geocodes. The first subdivision is jurisdictionLevel4.csv.
  • donor.csv: data package donors. Metadata of the institutions that provide official data.
  • donatedPack.csv: descriptors of the donated files.
  • packages (_packXX folders): hash and other externally stored file descriptors, as well as makefile and other process descriptors to decompress these files and take them to the database (PostregSQL)...

• /data/_out: system-generated results (output), that is, metadata created from the algorithms and statistics applied to the _pack data.
