What is in our mind

5

Integration = Data Sharing

take data form one digital archive

get a content enriched digital archive

integrate into other digital archive

Jen-Jou HungJen-Jou Hung

Provide Data on Internet for downloading Database Dump Technical Documents

After downloading data1. to understand the structure and logic of

downloaded data. 2. to write a program to transform the downloaded

data into the your data structure.3. to write another program to make sure the

transformation does not lost any required information.

6

The Most Common Data-Sharing Way

Jen-Jou HungJen-Jou Hung

1. Need time to understand data and write programs.

2. data won’t update automatically. To keep data fresh, continually migrating new data dump is required. (static share)

3. Once the data structure of the new release data dump changing, the data migrating program might need to be changed too.

7

The drawback of using data-dump-share

Jen-Jou HungJen-Jou Hung

A better model for sharing data:1. have an easy way to migrate data

into other system2. independent from the data structure

of source data3. data will be automatically updated

once the source changed (dynamic share)

Dynamic Data Sharing

Providing data access service instead of only data dump.

Project access required data through services No need to understand the complicate structure of

data in backend. Always get the newest data.
