See on p. 1 of ElectricManual.pdf that the Electric version is 6.08.
As known from the Electric download page [
https://www.staticfreesoft.com/productsFree.html ], there was an older
"C" version.
The "C" source code for electric-6.08.tar.gz is at [
http://ftp.gnu.org/pub/gnu/electric/ ].
I don't know what happened to the SDF. Maybe in the JAVA version it
became "Restore Waveform Window Configuration from Disk..." [
https://www.staticfreesoft.com/jmanual/mchap04-11.html ]. Though, Steve
can probably better comment on that.
I do not know in detail either what information is needed. Maybe the
following references can help:

particular, slide 17)

In the block diagram figures of the following documents it looks like
SPICE netlist, SPICE model, template data, and simulation output (from
SPICE program like HSPICE) may be needed for generating a .lib file:

Thanks!
I also found in some version of manual
http://eia.udg.edu/~forest/ElectricManual.pdf
(p. 231) on SDF file import:
"In the ALS simulator, you can also obtain simulation data from an SDF
file (with the SDF subcommand of
the Import command of the File menu). Once this data has been read,
one of three sets of values (Typical,
Minimum, or Maximum) must be selected from the Annotate Delay Data
(ALS) subcommand of the
Simulate command of the Tools menu.
"
Yet I do NOT see this menu in my Electric 9.0.7
Dmitry, Steven has it moved somewhere!?
With the sources pointed out it's not a big deal to code wrapper or
even translate
C code to Java.
Yet I do not have any idea which information from jelib must be used
for writing synopsys liberty file or howto create it with ALS/SPICE
and validate the generated info to be enougth to import Electric
GDS+.lib into Cadence genus/innovus..
.lib format parser may be implemented using
https://en.wikipedia.org/wiki/JavaCC and YACC grammar description from
C/C++ sourcses yet
