The document discusses the Global Land Tool Network's Social Tenure Domain Model (STDM) and its transition to an online platform. STDM is a land information tool that documents land tenure for formal and informal land rights. It is implemented using open-source software and aligned with the Land Administration Domain Model. Future development of STDM includes adding a file-based data store, online components, and security/privacy features to share data securely over the web. This will allow for online household surveys, mapping, reporting, and open data access to scale STDM's documentation of land rights.

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

6. GLTN BRIEFING AND PROGRAMME

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.

7. GLTN BRIEFING AND PROGRAMME

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.

The Information Tool
STDM has been implemented based on proven Open
Source software maintained by a broad community,
business investment and the non-profit foundational and
legal body of OSGeo.

Postgres

PostGIS

QGIS

Geraldo Reports

...and many more

Future Development
Future development of STDM is to add a file based option
for the data store (GeoPackage) and an Online service
component.
The work to get there entails three main aspects:

Adjust data store and data model

Add security and privacy layers

Add online components

11. GLTN BRIEFING AND PROGRAMME

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

Open Data Licenses

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...

Online
Architecture
The code system is
not changed. Con-
nectivity is adapted
to suit the require-
ments of an Online
system. Web ser-
vice software and
security compo-
nents are added as
needed.

14. GLTN BRIEFING AND PROGRAMME

Software and Standards
The system is based on Open
Source Software components
including (besides others):

Postgres / PostGIS

QGIS + MapServer

+ OpenLayers

+ Apache, etc.
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)
Open, Secure and Sustainable

Online interfaces
Use state of the art technology, minimize web traffic, support
older hardware and any platform.

Record Household Information

Mapping components

Report Generation

Anonymized Open Data Server
Going Online... (Prototype launch in 2016)

16. GLTN BRIEFING AND PROGRAMME

Conclusions
The Open Source development model has proven to be the right
choice for STDM. Standards help to build a sustainable and
open system which is:

Easy to Use

with Powerful Functionality

Extendable and Customizable

Interoperable and Standardized

Transparent and Secure
Community Adoption is in Progress
