The automatic interpretation of charts based on the Library of Interpretation Texts relies on thematic sets of citations which describe simple astrological situations, e.g. planet X in sign Y (what the planet in this sign means); aspects between planets (what this aspect of these planets means), and so on. The interpreter compiles (assembles) all the citations relevant to the situation existing in the chart without taking into account what is specific in a chart.
For more precise synthesis of an interpretation of a given chart, it is necessary to go beyond the simple schema just described (i.e. '[P.S]', '[P.A.P]'). A truly "universal interpretation" facility requires that any astrological situation, no matter how specific or complex, be describable to the interpreter. This is achieved by describing its conditions using astroformulae, i.e. the formula description language.
The markup of a book for universal interpretation differs from the markup of books about specific astrological themes.
For example, a book for universal interpretation may be formatted as follows:
// Sergey Wronsky. Astrology and profession.
asp = 0,60,90,120,180;
<<< SUN.ARI & SUN.H10,H11,H12 >>>
The Sun in Aries and birth at sunrise to noon:
<<< SUN.SCO & SUN.asp.PLU,MAR.r >>>
The Sun in Scorpio and in any aspect with Pluto or with retrograde Mars:
The salient differences are as follows:
It is convenient to create texts for universal interpretation using the "Edit Book" facility available from the popup menu of the Library of Interpretation Texts. The editing window includes functionality for checking the markup syntax of the edited text.
