From: pliuzzo While Photographic Collections as the Fotothek of the Bibliotheca Hertziana have many images of Inscriptions, or
-Drawings of inscriptions, Epigraphic Databases contain editions of inscriptions with images. This different perspective is a decisive one. The Photographic collection approaches the description of a photograph looking at what it represents and describes it within a description of an object. It is partial to the documentation and to the object. Epigraphic editions, even those with a more olistic approach are biased towards the text or at the best the support on which this is inscribed. There is of course richness within the encounter of the respective valid and complementary persepectives Metrical inscriptions may be intuitively associated with a more deep connection between text and context, but as these are not my field of research I will develop my argument on an example which is not immediately relevant to the topic, and I am certain metrical inscriptions experts will not fail to draw their own parallel cases. I claim only that there is no technological obstacle to a comprehensive linking across disciplines of information recorded and available online, which can be simply enriched with qualified links in the most common and widespread formats to deliver immediate important results with tools in in the hands of everyone. I claim only that there is no technological obstacle to a comprehensive linking across disciplines of information recorded and available online, which can be simply enriched with qualified links in the most common and widespread formats to deliver immediate important results with tools in the hands of everyone. Getting quality content in quality formats, with relevant semantics online, is a much more urgent and challenging task than implementing large infrastructures or newer technologies. I will try to show something which is not new, namely that different perspectives like those of a photographic collections and epigraphic databases, or the two worlds of knowledge available to researchers as "printed materials" and "online resources" building up in the web, are complementary: while both suffer the same issues (findability, accessibility, quality control, style) they both build knowledge by linking. Linkage in both ways from the web-based-and-digital world to the printed-material world are bidirectionaly faulty and hard to make without specific expertiese. FAIRwashing practices have made the complexity of this interrelation even more of an hinderance for researchers.

I will start from a record in the
Fototeca of the Bibliotheca Hertziana, follow its link into a website of the Photographic Collection of the Bibliotheca Hertziana, follow its link into a website of the Musei Capitolini and then move to the
Epigraphic Datanbase Rome. I will follow links from there to explore how much information can be actually connected to get the best possible knowledge of a single object. It should become evident how there is more real and direct value for the exploration of the network of informations in a argumentative knowledge graph connecting in one specific and non unique way these resources than there can be from the extraction of value from quantitavely collected data. It should become evident how there is more real and direct value for the exploration of the network of information in a argumentative knowledge graph connecting in one specific and non unique way these resources than there can be from the extraction of value from quantitatively collected data. The fragmentary nature of the data and the actual available data, scanty by nature, clashes in the end in front of the bibliographic barrier, that is, the innaccessibility of quality full texts of publications quoted as structured and unstructured data. This presentation is in itself an example of one such path, that I would like to call an argumentative knowledge graph (AKG). This paper with a simple tool like RDFa Play can be directly visualized as data and it can be imported as is into a triplestore. Here I parse the HTML with vis.js for some additional example representation of the embedded data. Not to claim their usefulness, as often happens, but to claim their uselessness de facto, compared to the actual argument which makes its way across this network without any further visualization need.

We cannot complain about it, we can confirm that the work to be carried out is still endless, and that the emergence of tools which spread uncontrolled information is going to be a major hindrance in the pursuit of knowledge. There is however an eminently huge gap in the information available which is hard to explain when looked at theoretically, but is easy to understand if one has ever entered information in a database or published resources online.

I think that the missing links, beside those of the alignment of vocabularies bibliographies and other so-called "controlled", but I would say, to date,s hardly "controllable" areas of information. These missing links are those related to the several layers of connections among the different individual statements that one can make collecting and organizing individual resources. I have thus made a second experiment. I have added to this text RDFa statements manually to link all statements and entities with each other explicitly with a standard vocabulary. This text becomes thus in a second way also a dataset.

RDFa encoding
RDF choices
RDFa can be encoded in many ways, here I have encoded only the following formats, to facilitate my own experiment. For example:
@resource @typeof
to declare a resource and assign it to a class. For example, resource="#bhpd71012" typeof="sch:ImageObject"
is an RDF statement which says that the entity "bhpd71012" is a ImageObject, aka, a photo. @resource @property @about
to declare relations between two entities. For example, resource="#bhpd71012" property="sch:isPartOf" about="#fotothek"
is an RDF statement that says that the entity called "bhpd71012" is part of the entity "@fotothek", which represent the Fototeca. @resource @property @about
to declare relations between two entities. For example, resource="#bhpd71012" property="sch:isPartOf" about="#fotothek"
is an RDF statement that says that the entity called "bhpd71012" is part of the entity "@fotothek", which represent the Fotothek. @property
alone connects the same parent entity to a textual value within the XHTML element. @resource @property @href
declares a relation with a resource defined outside of the current text. property="dc:relation"
- href="https://trismegistos.org/place/2058"
declares a relation with the trismegistos entity named in the @href attribute.span
