The document discusses the Social Tenure Domain Model (STDM) and plans for an online version called STDM-Online. STDM is a land information tool developed by GLTN to document land tenure, including informal and customary arrangements. STDM-Online will make this data available securely online using open-source software like PostGIS and open standards. It will allow users to record household information, map land parcels, and generate reports while hosting the software and maintaining the system. STDM aims to document land rights at a large scale affordably and promote more inclusive land administration systems.

The Global Land Tool Network (GLTN)
The Global Land Tool Network (GLTN) is an alliance global
regional and national partners.
• The main objective is to contribute to poverty alleviation
through land reform, improved land management and security
of tenure.
• UN-Habitat through GLTN works with partners including civil
society organizations, finance institutions, research and
training institutions, donors and professional bodies.
Most developing countries use conventional land administration
systems which cover less than 30 per cent of the country, leaving
up to 70 per cent of citizens looking to informal and/ or customary
approaches for their tenure security.

STDM – The Social Tenure Domain Model
The Social Tenure Domain Model (STDM) is a pro poor
land information tool following GLTN's core values and
principles:
●
Pro poor;
●
Equitable;
●
Sustainable;
●
Affordable;
●
Systematically large scale /scalable; and,
●
Gender-sensitive
While taking into consideration:
●
Good governance;
●
Subsidiarity; and,
●
The Continuum of Land Rights.

STDM – The Social Tenure Domain Model
The land information tool STDM focuses on three
facets:
1. STDM as a Concept
2. STDM as a Model
3. STDM as an
Information Tool

7. GLTN BRIEFING AND PROGRAMME
7/ 17
The STDM Concept
The concept of the Social Tenure Domain Model is to
bridge this gap by providing a standard for
representing ‘people – land’ relationships
independent of the level of formality, legality and
technical accuracy.
Bridging the Gap:
A Complimentary approach to customary and informal tenure.

8. GLTN BRIEFING AND PROGRAMME
8/ 17
The STDM Model
STDM is a ‘specialization’ of the ISO-approved Land
Administration Domain Model (LADM). LADM
development took place in parallel of the STDM
concept and model development.
Bridging the Gap:
Any form of right, responsibility or restriction in a formal system is
considered as a social tenure relationship in STDM.

9. GLTN BRIEFING AND PROGRAMME

Software Tools
The future development of STDM is to "Go Online".
The work to get there entails three main aspects:
●
Data and data model
●
Security and privacy
●
Online interfaces
Complementing the Desktop version with STDM Online...

10. GLTN BRIEFING AND PROGRAMME
10/ 17
Data and Data Model
The data model has to be sturdy and simple and easy
to import and export:
●
Keep aligned with LADM
●
Support OpenStreetMap
●
Stick to Standards
●
Data Licenses
Going Online...

11. GLTN BRIEFING AND PROGRAMME

Security and Privacy
Exposing the data on the Web requires a highly
secure environment, transparent policies and good
governance.
●
Secure Architecture
●
Open Governance
●
Transparent Terms of Service
Going Online...

State of the Art Open Source technology for reliable
and scalable services. Minimize web traffic with low
tech front end components, implements:
●
Record Household Information
●
Mapping and Digitizing Modules
●
Report Generation Modules
●
Anonymized Open Data Server

STDM Software and Standards
The system is based on Open
Source Software components
including (besides others):

Postgres / PostGIS

QGIS MapServer

OpenLayers

GDAL OGR
Open Standards help to keep
the infrastructure open,
including (besides others)

OGC SFS (Data format)

ISO LADM (Data Content)

OGC WMS (map content

OGC GeoPackage (transport)

STDM Online Hosting
●
Does not require installation
●
Software can be used as a fully integrated Service with:
●
Security updates
●
Maintenance
●
Updates
●
Backup
●
Export options
●
Service contract
●
Pay per use
●
Scale on demand

Conclusions
The Open Source development model has proven to be
the right choice for STDM and STDM Online.

Hosting option reduces up front effort

Flexible and scalable payment options

Customizable and extendible functionality

Transparent and secure service

Broader impact on local change
