Why use <title> in unstructured originalSource <bibl>

[ingoboerner]

<bibl type="originalSource">
                                    <author>Jakob Ayrer</author>: <title level="a">Tragedia Thesei, des zehenten Königs zu
                                        Athen, von den vierzehen Tributkindern, mit 41 Personen, hat 8 Actus</title>. In:
                                    <title level="s">Ayrers Dramen</title>. Herausgegeben von <editor>Adelbert von
                                        Keller</editor>. <biblScope unit="volume">Zweiter</biblScope> Band.
                                    <pubPlace>Stuttgart</pubPlace>: <publisher>Litterarischer Verein</publisher>
                                    <date>1865</date>, S. <biblScope unit="page" from="1207" to="1303"
                                        >1207–1303</biblScope>.</bibl>  

vs.

<bibl type="originalSource">
            <title>Goethes Werke. Hamburger Ausgabe in 14 Bänden. Textkritisch durchgesehen und mit
              Anmerkungen versehen von Erich Trunz, Hamburg: Christian Wegener, 1948 ff.
              [Seitenkonkordanz zu einer Mischauflage aus den Jahren 1959 und 1960.]</title>
          </bibl>

Why is the bibliographic reference in the second case wrapped in and an additional <title> element?

Thanks for pointing to this. This is just occurring in GerDraCor. The example below is still how TextGrid encoded the original sources, just by wrapping <title> around the entire bibl info. I am working retroactively to make this info better, like in the example above. We are actually using the bibl info in the metadata file (publisher, place, year and number of pages); the GerDraCor metadata table would be a good place to check how much is already updated (I'd guess around 30% of the files). New GerDraCor files are always encoded with richer bibl info, while I update older files from time to time (we're consulting actual print editions for this, which makes it so cumbersome 😊). It will still take some time, but on the long run, we want to update the thin bibl info from TextGrid for the whole corpus.
