Hi Lyubo,
One thing I'm not clear on is whether there is a pipeline from the Biodiversity Data Journal to GBIF. In other words, if I publish a data-rich paper in your journal, does it get automatically harvested by GBIF?

Not bad at all, and it is definitely a great thing to index and make these discoverable. Unfortunately, this comes with the trade-off and on the expense of inclusion of non-verified data as well. GBIF are still faraway from mobilization of the properly published "small" data (that is well documented in literature, peer-reviewed, registered for authorship and priority, citeable, etc.). Why it is so? Because of the same "markup" problem.

Nobody knows the real proportion between the "big" collections' data and "small" data, but according to some calculations, the "small" data constitute about 80 % of all data. In other words, the "small' data are in fact the "big" data. When GBIF will be able to gather the precious, peer-reviewed, small data from historical and recently published literature, for example? The answer is: "probably never", until we continue to publish in archaic way, such as paper/PDF, forgetting that someone should spend the huge effort to extract data from PDFs, put this data into a database and then upload it to GBIF or anywhere else...... while PDFs continue to pile up every day!

Why so? Again, because of the huge effort associated with markup, especially of complex biodiversity data types, such as occurrence records and morphological descriptions.

Any kind of occurrence records (and other types of small data) are published mandatory in both human-readable (HTML, PDF) and computer-readable (XML, Darwin Core and DwC Archive) formats. It is like a piece of cake to download or harvest data published in this way and to make them not just "discoverable via open access" or "linked to taxon names, mentioned in the same article", but REUSABLE!

Locating articles (i.e., the things we actually cite) in BHL is sometimes straightforward, but often it is anything but. Journals can change names, may have multiple names (sometimes in multiple languages), concurrent or inconsistent volume and/or page numbering, etc. Notions that we take for granted today (that there are "articles" and that they have explicit titles) may not hold, and off course every taxonomist knows that determining the data of publication can be a challenge (as I'm sure Neal Evenhuis, among others, will testify). Much of the time I spend on BioNames consists of taking cryptic, often misleading (if not downright erroneous) citations to original descriptions and matching these to BHL (or other sources).

For all the issues that you document in "A specialist’s audit of aggregated occurrence records" http://dx.doi.org/10.3897/zookeys.293.5111 , I could probably find equivalent horror stories for bibliographic data.

If we can go from a specimen to the associated literature we could then track some of the issues you mention, such as different identifications, discussion of whether the collection locality is correct, etc.

Given such a catalogue or index, you can go further and digitise and make available on the Web all the content. Cool, yes? Anyone anywhere with access to the Web can view a biodiversity publication at the click of a mouse. This works because biodiversity publications are very well-defined objects which either exist or don't. BHL is hugely valuable and 'intrinsically' successful because the goal of digitising all biodiversity publications is achievable, in principle.

Each record is instead an entry point into an investigation (minimally) of the identity of the organism(s) observed, of the location of the observation, of the timing of the observation, of the observer and of the fate of any specimen(s) or images which are hard evidence for the observation. I say 'minimally' because the museum records that wind up in GBIF often have more than these basics in their 'pre-GBIF' form, and are sometimes only condensed versions of even more information available elsewhere. You don't get that from GBIF.

It contains lots of errors, it's taxonomically, geographically, ecologically and 'literature-wise' grossly incomplete, and for many biodiversity studies (see Meier and Dikow) you're better off starting with your own plan of attack and chasing sources independently.

GBIF has taken an easier approach and has been accumulating records as though they were coins, and measuring its usefulness by counting its 'wealth' of records, so that if it has twice as many records it must be twice as useful, right? Other people in this thread have pointed out how raw counts are meaningless for assessing usefulness. Here I just wanted to say that what works for BHL doesn't work for GBIF, because the items being made Web-available are inherently different.
