Hi Laurent and Phil,

Thank you very much for your comments! We are glad to include a statement
on the final version of the document
concerning the need of further advice in specific areas.

As Phil mentioned, there is much more to be done and discussed about these
topics. We hope to continue with the discussions and if possible to
contribute with other working groups. It would also be great to work on
complementary material for the DWBP document.

kind regards,

> Privacy
> =======
> Things like preparing and publishing a Privacy Impact Assessment, like the

> from the document's intro:
> "Not all data and metadata should be shared openly, however. Security,
> commercial sensitivity and, above all, individuals' privacy need to be
> taken into account. It is for data publishers to determine policy on which
> data should be shared and under what circumstances. Data sharing policies
> are likely to assess the exposure risk and determine the appropriate
> security measures to be taken to protect sensitive data, such as secure
> authentication and authorization."
> API Keys
> ========
> It's true, there is no mention of API Keys, however, the doc does point to
> a number of frameworks and sources of info that do support them.
> Vocabulary choices
> ==================
> On vocabulary choices, the BP doc points to earlier work on this
> https://www.w3.org/TR/ld-bp/#VOCABULARIES in which a number of points are
> made. What the paper you point to refers to as Frankenstein ontologies

> "Vocabularies should be used by other datasets
> If the vocabulary is used by other authoritative Linked Open datasets that
> is helpful. It is in re-use of vocabularies that we achieve the benefits of
> Linked Open Data. Selected vocabularies from third parties should be
> already in use by other datasets, as this shows that they are already
> established in the LOD community, and thus better candidates for wider
> adoption and reuse.
> For example: An analysis on the use of vocabularies on the Linked Data
> cloud reveals that FOAF is reused by more than 55 other vocabularies."
