<div dir="ltr"><div>Hi Marion,</div><div><br></div><div>Interesting question and rather multi-faceted. The "quality" of DDI metadata can be viewed in terms of coverage and content. More has been done in terms of content but in an informal way. From the beginning DDI determined what was needed in terms of object coverage based on norms in the social sciences and particularly social sciences archives (preservation and discovery). The intent (see a great presentation by Ann Green at NADDI 2014) was to cover the objects needed to inform the future user regarding where the data came from and how applicable it was to the intended use. This is way beyond discovery and technical usability, it goes into the intent of the data and features of the methodology, collection and processing which may affect its suitability for use. </div>
<div><br></div><div>DDI initially covered all the content of a "well constructed" codebook for a social science data file. We have extended this over the years to provide additional information on provenance (exactly how data was processed) and collection information. Currently we are working on including additional sources of data, development of data capture content (question development and testing, biomarkers, qualitative data etc.). Over the years this has been a bit of give an take. DDI has been treated as input to documents covering metadata quality as well as learning from them. </div>
<div><br></div><div>Currently we are working with the NSIs creating the Generic Statistical Information Model (GSIM) which is informed by the metadata Quality Frameworks of their organizations. We are making sure we both reflect the recommended content as well as provide a means of linking to these Quality Frameworks and how they impact the content and quality of the metadata and data described in DDI.</div>
<div><br></div><div>With all of that there has been little formal review of how well the coverage of DDI reflects the recommended coverage within various data communities. This should probably be formalized.</div><div><br>
</div><div>As for the content of metadata expressed in DDI there has been no work that I am aware of. Others may be more involved in this area than I am. </div><div><br></div><div>Hopefully others will jump into this conversation as it is an important one. Not only for users in general but for the DDI community in terms of advancing the use of DDI and in informing potential users of its applicability in terms of meeting the requirements of quality frameworks within their own field.</div>
