How should Open data portals be evaluated?

Building a successful Open data portal can effectively help the public sector drive public data openness, but what kind of Open Data portal is successful? What indicators can be used as an Open data portal evaluation standard? Perhaps the following international Open Data evaluation system is widely used to give the answer.

Sunshine Fund Evaluation system

The Sunshine Fund (Sunlight Foundation) is a non-profit organization designed to promote government transparency in the United States. 2011, the Sunshine Fund proposed 10 standards, and thus established the U.S. government Open Data portal evaluation system.

The Sunshine Fund believes that the data sets published in the Open data portal must meet the following conditions:

1, Integrity: the integrity of the data set reliable, complete, file format available for download;

2, the original: including the source of statistical data collection;

3, timeliness: data real-time to ensure its use of value;

4, usability: To meet as many users and uses;

5, can develop: can be developed through the computer and reuse;

6, Non-discriminatory: All persons are available, without any preconditions or registration requirements, no privileged use or exclusive use;

7, no ownership restrictions: The file format of the dataset no one or institution has exclusive control (in fact, some open but proprietary formats are not encouraged, such as Excel files and the PDF file is not conducive to reuse);

8, freedom of law: not subject to third party copyright, patent, trademark or trade secret restrictions;

9, permanent: Data set at any time to query and use and unlimited time limit;

10, low cost: free or lowest price use dataset.

Some of the indicators in the system have been implemented in some countries ' open data portals, such as free and availability, but there are still a number of indicators to achieve a greater degree of difficulty, especially the DataSet is permanent (some of the dataset may change the name or address over time), file format without ownership restrictions.

Second, five-star evaluation system

The five-star evaluation system, proposed by Tim Berners, a British computer scientist, is based on the application of Open data format types and Semantic Web standards, with a minimum rating of five stars for the highest rating.

The details are as follows:

The evaluation system emphasizes the importance of data set, such as permanence, interoperability, link and so on, which is the most common in the world.

Iii. The French Open Data Association evaluation system

The French Open Data Association was established in 2013 to bring together open data-related organizations across France. The association has launched a list of good practices for Open data as a reference to open data portal construction and a post-construction evaluation standard. The list contains 72 excellent examples, grouped into six categories: Web Maintenance, DataSet cataloging, file formats, open License agreements, dataset transparency and availability, and privacy protection.
