GEOSS does not own the data that is integrated in the GCI but data remains in the members and participant organizations data provider services. In the past, GeoViQua developed the concept of a data label (the so called GEO Label) as a graphic aimed at represents a set of common principles that a dataset part of GEOSS should aim to respect. The label had 8 facets with 8 icons each one show if a principle is followed by illuminating it with color. These eight principles were extracted as the results of 3 surveys conducted by GeoViQua among the GEO community and beyond. We deliberately selected 8 facets that could be automatically calculated from the metadata about the data and a data label could be associated to each dataset in www.geolabel.net. This is referred in this document as the GeoViQua label.
Recently, the data management principles (DMPs) were adopted by the GEO Plenary giving us 10 principles that GEOSS providers are encouraged to follow to better conform to GEO requirements. In practice, a dataset that follows the DMPs is considered a good GEOSS dataset. Many of the DMPs can be tested by reading the metadata about them, other cannot directly but it seems that can be also tested by other means.
The data label proposed here (the DMP label) is a fusion of the GeoViQua label and described in www.geolabel.info and the 10 criteria provided by the DMP framework. The principles can also be represented by 10 icons. The principles are classified in 5 categories that can be represented by colors. The possibility of generating the label automatically from metadata and data access need to be explored.
The DMP 10 proposed facets
Presenting the label together in a single graphic
GeoViQua surveys also showed that a round representation is preferred by the users. The logos has to be always present but the background color is applied if the individual DMP is followed by the dataset.
Proposed DMP label
The proposed DMP Label has 10 facets and uses 10 icons in it. As shown before, some of them can be directly adapted from the GeoViQua label and others are proposed directly here:
We propose the same disposition of logos as in the GeoViQua label but instead of 45 degree facets, 36 degree facets are required. The background color depends on the 5 groups defined by the DMPs. The background color of the facet is applied only if the individual DMP is followed by the dataset.
The central part is always white and has the GEO logo and the “DMP” 3 characters in a font to be determined.
(we need some help on the exact final design of the label and also on in providing and example on how the complete label looks like)
How the label will be generated and the three level of the Data label
Level 1: The providers declare that they are following some or all of the principles and use the label to expose what they believe is the level of conformance to them in their outreach materials.
Level 2: The providers are able to generate a label for each dataset by an automatic conformance test that accesses both the metadata and the data. The criteria used by the automatic conformance process are made public so, providers can improve the metadata to get a better conformance result.
Level 3: The provider agrees with the result of the conformance test and requests and receives a certification. The 3 levels do not need to be implemented in GEO yet but is good to have them as a reference. Eventually Level 2 and level 3 can be delegated to a certification entity such as an independent SME.
