Issue 471: graphical examples

Posted by Martin on 30/1/2020

Hi Carlo,

Great!! Could you provide us with some inspirations from your graphical language?

I prefer the time line, rather that snapshot sequences, didactically to make clear that simultaneity and linearity of causality is an illusion. It does not render the richness of space, but there is a good practice in archaeology to depict the spacetime volumes of periods in graphs with a sing space dimension.

I believe we should refer to such a publication in the introduction.

Dear all,

I attach my graphical rendition of the first canto of Orlando Furioso. Every character is a continuous line. Although it incorporates space and time in a single foil, it does not let the reader appreciate the real temporal development of events, i.e., if you draw a vertical line that intersects all 5 characters you do not get the correct representation of who was where at that time. So it’s an approximation.

If you happen to know a professional way of doing this, I’d appreciate the info.

It's not doing any better job at delivery correct answers when drawing a line but I could not help thinking of the following:

Andew DeGraff's posters:

Something a bit more relevant with time and events:

and a machine made version here:

I hope these are relevant.

All correct!

I'll produce a color proposal(Laokoon) for the whole CRM class hierarchy. It is not good to see only parts. For instance, Persistent Item will never appear in an instance diagram. Therefore its color is relatively irrelevant.

Dear George,

Your arguments well taken, I still want to point out that there was no decision of CRM-SIG yet, that we have agreed on a competition and that concerns about the quality of published documents should be answered.

We talk about publication of the authoritative text, didactic material about the schema, and graphical representation of instances. we need to decide if we follow one or two styles.

We do also have a large set of graphics in the style presented in authoritative document. I would like to understand better, what the amount of material is in the community of use you talk about, and who is involved and what sort of material it is. We always do respect  communities of use. Whatever the decision, one has to adapt.

I do not agree that color attribution is arbitrary. If it were arbitrary, no standard would be needed.

So, please inform as better...

It was my recollection that at the last meeting we actually agreed the colours and that this changed in our email thread. However, the competition is fine; I trust the process.

Groups that I know of that use this already are: LinkedArt, SARI, Pharos, CHIN, CIDOC conferences for the last three years, MASA in France. Documentation is not just done at the model level but at the mapping level, so we are talking about hundreds of diagrams with thousands and thousands of representations.

On colour, Goethe believed the following:

> Goethe also included aesthetic qualities in his colour wheel, under the title of "allegorical, symbolic, mystic use of colour" (Allegorischer, symbolischer, mystischer Gebrauch der Farbe), establishing a kind of color psychology. He associated red with the "beautiful", orange with the "noble", yellow to the "good", green to the "useful", blue to the "common", and violet to the "unnecessary". These six qualities were assigned to four categories of human cognition, the rational (Vernunft) to the beautiful and the noble (red and orange), the intellectual (Verstand) to the good and the useful (yellow and green), the sensual (Sinnlichkeit) to the useful and the common (green and blue) and, closing the circle, imagination (Phantasie) to both the unnecessary and the beautiful (purple and red).[26]

https://en.wikipedia.org/wiki/Theory_of_Colours#Goethe's_colour_wheel

whereas in Chakra theory the following is true

> It is believed that each Chakra has a particular colour. The base or Root Chakra is red, it makes you more alert, increases circulation to all tissues, warms and awakens. The second Chakra above, the Sacral Chakra, is orange, the color of joy and wisdom, energy and internal connection. By applying orange to you sacrum and choosing Yoga poses for this region may balance your digestion.
> The next above is the Solar Plexus Chakra and it is yellow corresponding to self worth, personality and ego. Green is for the Heart chakra, it is healing and loving by nature, making you grateful for giving and receiving. The colour of the Throat Chakra is blue used for matters relating to speech and communication. The Brow (sometimes known as the 3rd eye) Chakra and it is Indigo. Concentrating on the “3rd eye” point during Yoga practice and Meditation will help enhance self responsibility and intuition. The last is the Crown Chakra and it is bright white, although colors of violet and gold are also seen in this area. Violet energy brings about increased feelings of spiritual connection, intuition and mental clarity, often helpful in emotional problems.

My favourite philosopher had the following ideas on colour

> For by convention colour exists, by convention bitter, by convention sweet, but in reality atoms and the void

Here is a pop culture reference on the meanings of colours, pink means ‘girlish’ etc.

https://www.empower-yourself-with-color-psychology.com/meaning-of-colors...

Anyhow, there are strategic reasons for choosing the arbitrary colours we chose given prevailing cultural prejudice in the West towards what a colour might mean, which is what we originally based the extant colour division on. The parts of the model that are different in ontological nature should have sufficiently different colours in the spectrum so that they are not confused with one another. Different part of colour spectrum = different kind of thing. Red was not used at all because it is the colour of STOP, violence, do not go further, whereas blue was chosen as a central colour as it is easy to look at and promote tranquility. When staring at CRM graphs, we ought to facilitate such calm. Brown is an earthy colour connoting things of a more material nature. etc. etc.

Anyhow, I guess we should just save the colour conversation for the in person meeting since I think we will just end up having to vote.

Dear George,

Nice graphics. I would like to see the color choices actually in the same layout. Otherwise we confuse layout and color. The Laookon example does not have the additional representation links because I wanted to focus on the ones introduced in the text.

By the way, may I remind everybody that our SIG rule is, that no proposal can be decided in the same meeting it was proposed. It can only be accepted as a proposal. Decisions can only be taken on issues that have been formulated in a decidable form before the meeting, originally 14 days. No decision can be undone in the same meeting. If this is not fixed somewhere in text, it should be.

Dear All,

For true comparison, please see attached George's colors and two proposals of mine. We need to compare exactly the same layout. Layout rules are a different issue...:-)

I have been referring to psychological experiments of the 1970's, studying reactions to colors. Indeed, blue lowers blood pressure and red raises. Red is a color of activity and alert. Not "stop", but attention. Red stands out most from all colors. Whatever hue of red. My point is the event orientation of the CRM. In a knowledge graph, does it immediately render the message? Is the contrast good enough? Is the difference worth discussing it?

To be discussed:-)
