Theme
Local Data
Local data is where the universal promise of open knowledge meets the specificity of an actual place.
On Sunday, 9 March 2025, I attended Open Data Day Taiwan at National Taipei University's Sanxia Campus. Wikidata Taiwan organized the gathering around the theme of local data, a compact phrase that carries a large institutional question: who is responsible for making a place legible?
At the time, I was living in Taiwan and studying interaction design at National Cheng Kung University. Much of my work already sat between public information, digital products, sustainability, and civic systems. The event gave those concerns a shared room and a clearer vocabulary.
The public layer beneath everyday life
A city is full of facts that become infrastructure when they connect
Addresses, bus stops, schools, trails, public buildings, historical names, administrative boundaries, cultural sites, accessibility information, and local organisations may appear to be separate records. Once structured and linked, they form a public layer that supports maps, research, journalism, services, archives, and future interfaces that have not yet been designed.
Wikidata makes this especially visible because it treats knowledge as a graph of entities and relationships. A place can be connected to several names, languages, coordinates, institutions, dates, classifications, and external identifiers. The value grows through connection, provided that the data remains understandable and maintained.
What stayed with me
Four principles for designing with open local data
01
Local data needs local stewards
A dataset remains useful when people close to the subject can correct names, add context, notice omissions, and explain how a place actually works. Stewardship is a continuing civic role rather than a one-time upload.
02
Structure determines what can be found
Public information becomes more powerful when entities, locations, dates, identifiers, and relationships can be understood by both people and machines. Good structure turns isolated facts into navigable knowledge.
03
Coverage is a design decision
Every database reflects choices about which places, languages, institutions, and communities deserve detail. Missing data can quietly reproduce the same geographic and cultural inequalities found elsewhere.
04
Maintenance creates public value
The visible interface attracts attention, but long-term value comes from verification, documentation, compatible formats, stable identifiers, and patient correction. Maintenance is where public trust accumulates.
The Taiwan perspective
Local knowledge carries language, history, and administrative reality
Taiwan makes the politics of local data easy to see. The same place may carry Traditional Chinese, romanized, Indigenous, Japanese-era, historical, colloquial, and administrative names. A single official label can flatten that history. A well-designed knowledge system can preserve several layers while still giving applications stable references.
This matters far beyond cultural description. Search, navigation, emergency information, archives, tourism, public participation, and AI systems all inherit the quality of the underlying records. When local knowledge is absent or poorly structured, the resulting interfaces appear neutral while quietly giving some places more visibility than others.
Looking back from HAAM
Open data becomes durable through design, governance, and care
The strongest lesson was that public data has a user experience long before anyone opens an app. Naming, categorization, provenance, language coverage, permissions, update routines, and error correction all shape what people can eventually find and trust.
That idea continues through HAAM's work on accessible interfaces, civic technology, public information, and projects such as the reconstruction of wifi.ee. A map or directory may look like a collection of points. Its real substance is the institutional practice that keeps each point meaningful.
Open Data Day Taiwan 2025 made that practice visible. Local data becomes public infrastructure when communities can maintain it, systems can exchange it, and future users can understand where it came from.
