## Outline

  <!-- .slide: data-background="https://upload.wikimedia.org/wikipedia/commons/thumb/1/1f/Wikidatacon_2023_Banner_-_04.png/1024px-Wikidatacon_2023_Banner_-_04.png" data-background-opacity="0.5"-->
  
* OpenStreetMap and Wikidata
* Villages: all done!
* Address: 9 cities and counties
* School: mostly metadata editing 
* Emergency Shelter

Note:
Here is today's speech outline. I will talk about some general information of OpenStreetMap and Wikidata in Taiwan. Then the villages dataset, rivers dataset, school dataset, and the global OpenStreetMap community maintained name suggestion index.

* Monthly Meetup in Taipei, co-host of OpenStreetMap Taiwan and Wikidata Taiwan
* members overlapped with each other
* Major change monitor and mapping, tagging scheme discussion

Note:
I am one of the co-host of the monthly meetup in Taiwan, co-hosted with Wikidata Taiwan community. There are a hugh overlapped of community members between Wikidata and OpenStreetMap in Taiwan. The OpenStreetMap Taiwan community keep track of major development site, and sometimes discuss tagging scheme of mapping in Taiwan.

Note:
Sometimes Chinese people are making unrealistic edit, for example, cross Taiwan Strait Railway. It might be possible to add as proposal status, but most editor not aware about it. Might have trouble to distigish real and imagal status

## Villages in Taiwan

* inspired by serv [Barangay](https://en.wikipedia.org/wiki/Barangay) mapping projects, I want to told Taiwan story of mapping villages
* total number is 7,748
* mapped by community members in 4 years
* linked with government ID and Wikidata

Note:
Inspired by Serv, also known as Eugene, have started mapping Barangay in the Phillipines. I want to told Taiwan story of villages mapping. The OpenStreetMap Taiwan community took fours years to map every villages in Taiwan. The total number of villages is 7,749(date: 2022 7/1). And all villages are linked with government ID and Wikidata items

## The history of create Taiwan Villages' data on Wikidata

  <!-- .slide: data-background="https://upload.wikimedia.org/wikipedia/commons/thumb/1/1f/Wikidatacon_2023_Banner_-_04.png/1024px-Wikidatacon_2023_Banner_-_04.png" data-background-opacity="0.5"-->
  
* Start at 2019
* The fundemental geograph unit
* Using Taiwan Government Datasets
* New Porperty [Household Register System ID - P5020](https://www.wikidata.org/wiki/Property:P5020)

Note:
臺灣遮的村里資料是對2019年開始，村里是臺灣上基本的政治地理單位(忽略鄰一个通常無GSI範圍的單位)。是根據政府的開放資料來建立，嘛順紲共戶役政代碼提案屬性 P5020

## Monitor new or dissolve village in TW

  <!-- .slide: data-background="https://upload.wikimedia.org/wikipedia/commons/thumb/1/1f/Wikidatacon_2023_Banner_-_04.png/1024px-Wikidatacon_2023_Banner_-_04.png" data-background-opacity="0.5"-->

Note:
The community have set up a tools to monitor government dataset, if there is new entries or remove entries, we could make correspond edit on both Wikidata and OpenStreetMap.

## The Challenge of Up-to-date Village list

  <!-- .slide: data-background="https://upload.wikimedia.org/wikipedia/commons/thumb/1/1f/Wikidatacon_2023_Banner_-_04.png/1024px-Wikidatacon_2023_Banner_-_04.png" data-background-opacity="0.5"-->
  
* Currently static mode, small mirror edit needs
* Keep track of government dataset
* Communtiy hurry to add stuffs
* Much easier to add on Wikidata
* Have to Wait for date of the new villages established, then create new villages relation on OSM

Note:
It is quite a hard work to keep both OpenStreetMap and Wikidata up-to-date to the newest government dataset. You have to add the new villages in time, and label the revoked villages in time. It is much easier to edit Villages on Wikidata due to you don't have to edit on the effect date. But for OpenStreetMap, you have to change the villages after the effect date.

## Rivers' Challenge

  <!-- .slide: data-background="https://upload.wikimedia.org/wikipedia/commons/thumb/1/1f/Wikidatacon_2023_Banner_-_04.png/1024px-Wikidatacon_2023_Banner_-_04.png" data-background-opacity="0.5"-->
  
* Small creeks have little documents
* Adding [OpenStreetMap relations](https://wiki.openstreetmap.org/wiki/Relation) are not easy 
* Rivers with government ID are just Small portation 
* [Cebuano Wikipedia](https://en.wikipedia.org/wiki/Cebuano_Wikipedia) bot created articles chaos

Note:
Now it is the second part: the river story. We have to admit, editing OpenStreetMap relation is a hard job, not easy for new-comers. Sometimes we have to survey to get rivers' data.

## [Name Suggestion Index](https://wiki.openstreetmap.org/wiki/Name_Suggestion_Index)

* A side project belongs to iD, starting at October, 2013, with little attention
* An independent project in  2019: [State of the Map US 2019](https://2019.stateofthemap.us/program/sat/mapping-brands-with-the-name-suggestion-index.html) Announcement

Note:
Name Suggestion Index 是 2013 年 10 月開始的，附屬 OpenStreetMap 編輯器 iD 經營的，2019 年獨立出來。頭起先 NSI 是無人顧的 side project

* language-independent, using Wikidata for mapping
* made OSM object unification tagging under the same brand

Note:
NSI 希望會當解決迒語言的問題，用 Wikidata 來做精確對應。向望編輯遮會當靠 NSI 予連鎖商家標示統一

* Announcement of New Schools esablished
* Duplicated items imported from Japanese Wikipedia
* Items with Wikidata tag: 2,489

Note:
對 2019 年了後，無啥更新。Wikidata 遐有新設立的學校，是看著新聞去加的，抑是有人佇 OpenStreetMap 加添。除了更新資料以外，另外有日語維基遐重疊，毋過無偌濟。

## Challenges for all kind of Data

  <!-- .slide: data-background="https://upload.wikimedia.org/wikipedia/commons/thumb/1/1f/Wikidatacon_2023_Banner_-_04.png/1024px-Wikidatacon_2023_Banner_-_04.png" data-background-opacity="0.5"-->

* Update village data to keep up to date to government village dataset (help from Plantoid's tools)
* add more river relations
* Fundemental platform, hard working not easy to catch the spotlight
* Multilingual
* Need contribution~~fundraising~~、~~human resource~~

Note:
There are some added or removed villages by Taiwan government in 2022, so OpenStreetMap and Wikidata Taiwan community have to change corresponded OSM relations and Wikidata items.
The big rivers' tribunties are added one by one by creating waterway relations for the creeks.
The data quality is a big problem. OpenStreetMap and Wikidata are quite fundemental platform in most people view. And the multilingual part need people who speak the language to help. Need people, need funding!

## Future Plan - Action

  <!-- .slide: data-background="https://upload.wikimedia.org/wikipedia/commons/thumb/1/1f/Wikidatacon_2023_Banner_-_04.png/1024px-Wikidatacon_2023_Banner_-_04.png" data-background-opacity="0.5"-->

* Theme workshops
* Mapping OpenStreetMap river relation to Wikidata items
* Adding multilingual labels on Wikidata river items, including Taiwanese Hokkian, Taiwanese Hakka, [Formosan Languages](https://en.wikipedia.org/wiki/Formosan_languages) names

Note:
Even during the COVID-19 pandamic, we still want to hold theme workshop to teach new-comer how to edit OpenStreetMap. And finally to edit rivers, and link to other database like Wikidata. Taiwan have a new law to preserve National languages including Taiwanese Hokkien, Taiwanese Hakka, Formosan languages. And we want to add these National Languages to both OpenStreetMap and Wikidata.
