+    “Software, instructions that tell a computer what to do. 
+    Software comprises the entire set of programs, procedures, and routines 
+    associated with the operation of a computer system. 
+    The term was coined to differentiate these instructions 
+    from hardware—i.e., the physical components of a computer system.”

+Title:
+ Archiving and Referencing all the source code towards recognizing software in academia
+
+Abstract:
+
+Software source code is everywhere, with tens of millions of developers
+worldwide, and it is of paramount importance to provide a universal
+archive and reference system for all its applications. Software Heritage
+has taken over this task.
+
+Software is, together with articles and data, a key ingredient of academic
+research, in all fields, hence preservation of, and access to the source code of
+Computer programs is a pillar of Open Science, and a necessary step to
+understand, verify, adapt and reuse the tools that we produce and use in the
+scholarly world.
+
+In this talk, we will present Software Heritage, a universal long term archive
+specifically designed for software source code that provides intrinsic
+identifiers for all the artifacts it stores, at all granularities, down to the
+level of the line of code. Software Heritage is now providing the infrastructure
+for depositing and referencing software source code, in collaboration with
+national and international open access portals.
