-------
30+
31+
Psylon is a Pylon v2 fork, tuned to behave like its predecessor snek-functions
32+
and laser-focused on seamless microservice interoperability.
33+
34+
Unlike Pylon v3, which aims to become a full-stack framework, Psylon is and
35+
will remain a GraphQL-based microservice framework. Security fixes and
36+
compatible behavioural changes from Pylon v3 that improve the v2 runtime will
37+
be backported to Psylon where appropriate.

This European Union Public Licence (the ‘EUPL’) applies to the Work (as
24+
defined below) which is provided under the terms of this Licence. Any use of
25+
the Work, other than as authorised under this Licence is prohibited (to the
26+
extent such use is covered by a right of the copyright holder of the Work).
27+
28+
The Work is provided under the terms of this Licence when the Licensor (as
29+
defined below) has placed the following notice immediately following the
30+
copyright notice for the Work: “Licensed under the EUPL”, or has expressed by
31+
any other means his willingness to license under the EUPL.
32+
33+
1. Definitions
34+
35+
In this Licence, the following terms have the following meaning:
36+
— ‘The Licence’: this Licence.
37+
— ‘The Original Work’: the work or software distributed or communicated by the
38+
‘Licensor under this Licence, available as Source Code and also as
39+
‘Executable Code as the case may be.
40+
— ‘Derivative Works’: the works or software that could be created by the
41+
‘Licensee, based upon the Original Work or modifications thereof. This
42+
‘Licence does not define the extent of modification or dependence on the
43+
‘Original Work required in order to classify a work as a Derivative Work;
44+
‘this extent is determined by copyright law applicable in the country
45+
‘mentioned in Article 15.
46+
— ‘The Work’: the Original Work or its Derivative Works.
47+
— ‘The Source Code’: the human-readable form of the Work which is the most
48+
convenient for people to study and modify.
49+
50+
— ‘The Executable Code’: any code which has generally been compiled and which
51+
is meant to be interpreted by a computer as a program.
52+
— ‘The Licensor’: the natural or legal person that distributes or communicates
53+
the Work under the Licence.
54+
— ‘Contributor(s)’: any natural or legal person who modifies the Work under
55+
the Licence, or otherwise contributes to the creation of a Derivative Work.
56+
— ‘The Licensee’ or ‘You’: any natural or legal person who makes any usage of
57+
the Work under the terms of the Licence.
58+
— ‘Distribution’ or ‘Communication’: any act of selling, giving, lending,
59+
renting, distributing, communicating, transmitting, or otherwise making
60+
available, online or offline, copies of the Work or providing access to its
61+
essential functionalities at the disposal of any other natural or legal
62+
person.
63+
64+
2. Scope of the rights granted by the Licence
65+
66+
The Licensor hereby grants You a worldwide, royalty-free, non-exclusive,
67+
sublicensable licence to do the following, for the duration of copyright
68+
vested in the Original Work:
69+
70+
— use the Work in any circumstance and for all usage,
71+
— reproduce the Work,
72+
— modify the Work, and make Derivative Works based upon the Work,
73+
— communicate to the public, including the right to make available or display
74+
the Work or copies thereof to the public and perform publicly, as the case
75+
may be, the Work,
76+
— distribute the Work or copies thereof,
77+
— lend and rent the Work or copies thereof,
78+
— sublicense rights in the Work or copies thereof.
79+
80+
Those rights can be exercised on any media, supports and formats, whether now
81+
known or later invented, as far as the applicable law permits so.
82+
83+
In the countries where moral rights apply, the Licensor waives his right to
84+
exercise his moral right to the extent allowed by law in order to make
85+
effective the licence of the economic rights here above listed.
86+
87+
The Licensor grants to the Licensee royalty-free, non-exclusive usage rights
88+
to any patents held by the Licensor, to the extent necessary to make use of
89+
the rights granted on the Work under this Licence.
90+
91+
3. Communication of the Source Code
92+
93+
The Licensor may provide the Work either in its Source Code form, or as
94+
Executable Code. If the Work is provided as Executable Code, the Licensor
95+
provides in addition a machine-readable copy of the Source Code of the Work
96+
along with each copy of the Work that the Licensor distributes or indicates,
97+
in a notice following the copyright notice attached to the Work, a repository
98+
where the Source Code is easily and freely accessible for as long as the
99+
Licensor continues to distribute or communicate the Work.
100+
101+
4. Limitations on copyright
102+
103+
Nothing in this Licence is intended to deprive the Licensee of the benefits
104+
from any exception or limitation to the exclusive rights of the rights owners
105+
in the Work, of the exhaustion of those rights or of other applicable
106+
limitations thereto.
107+
108+
5. Obligations of the Licensee
109+
110+
The grant of the rights mentioned above is subject to some restrictions and
111+
obligations imposed on the Licensee. Those obligations are the following:
112+
113+
Attribution right: The Licensee shall keep intact all copyright, patent or
114+
trademarks notices and all notices that refer to the Licence and to the
115+
disclaimer of warranties. The Licensee must include a copy of such notices and
116+
a copy of the Licence with every copy of the Work he/she distributes or
117+
communicates. The Licensee must cause any Derivative Work to carry prominent
118+
notices stating that the Work has been modified and the date of modification.
119+
120+
Copyleft clause: If the Licensee distributes or communicates copies of the
121+
Original Works or Derivative Works, this Distribution or Communication will be
122+
done under the terms of this Licence or of a later version of this Licence
123+
unless the Original Work is expressly distributed only under this version of
124+
the Licence — for example by communicating ‘EUPL v. 1.2 only’. The Licensee
125+
(becoming Licensor) cannot offer or impose any additional terms or conditions
126+
on the Work or Derivative Work that alter or restrict the terms of the
127+
Licence.
128+
129+
Compatibility clause: If the Licensee Distributes or Communicates Derivative
130+
Works or copies thereof based upon both the Work and another work licensed
131+
under a Compatible Licence, this Distribution or Communication can be done
132+
under the terms of this Compatible Licence. For the sake of this clause,
133+
‘Compatible Licence’ refers to the licences listed in the appendix attached to
134+
this Licence. Should the Licensee's obligations under the Compatible Licence
135+
conflict with his/her obligations under this Licence, the obligations of the
136+
Compatible Licence shall prevail.
137+
138+
Provision of Source Code: When distributing or communicating copies of the
139+
Work, the Licensee will provide a machine-readable copy of the Source Code or
140+
indicate a repository where this Source will be easily and freely available
141+
for as long as the Licensee continues to distribute or communicate the Work.
142+
143+
Legal Protection: This Licence does not grant permission to use the trade
144+
names, trademarks, service marks, or names of the Licensor, except as required
145+
for reasonable and customary use in describing the origin of the Work and
146+
reproducing the content of the copyright notice.
147+
148+
6. Chain of Authorship
149+
150+
The original Licensor warrants that the copyright in the Original Work granted
151+
hereunder is owned by him/her or licensed to him/her and that he/she has the
152+
power and authority to grant the Licence.
153+
154+
Each Contributor warrants that the copyright in the modifications he/she
155+
brings to the Work are owned by him/her or licensed to him/her and that he/she
156+
has the power and authority to grant the Licence.
157+
158+
Each time You accept the Licence, the original Licensor and subsequent
159+
Contributors grant You a licence to their contributions to the Work, under the
160+
terms of this Licence.
161+
162+
7. Disclaimer of Warranty
163+
164+
The Work is a work in progress, which is continuously improved by numerous
165+
Contributors. It is not a finished work and may therefore contain defects or
166+
‘bugs’ inherent to this type of development.
167+
168+
For the above reason, the Work is provided under the Licence on an ‘as is’
169+
basis and without warranties of any kind concerning the Work, including
170+
without limitation merchantability, fitness for a particular purpose, absence
171+
of defects or errors, accuracy, non-infringement of intellectual property
172+
rights other than copyright as stated in Article 6 of this Licence.
173+
174+
This disclaimer of warranty is an essential part of the Licence and a
175+
condition for the grant of any rights to the Work.
176+
177+
8. Disclaimer of Liability
178+
179+
Except in the cases of wilful misconduct or damages directly caused to natural
180+
persons, the Licensor will in no event be liable for any direct or indirect,
181+
material or moral, damages of any kind, arising out of the Licence or of the
182+
use of the Work, including without limitation, damages for loss of goodwill,
183+
work stoppage, computer failure or malfunction, loss of data or any commercial
184+
damage, even if the Licensor has been advised of the possibility of such
185+
damage. However, the Licensor will be liable under statutory product liability
186+
laws as far such laws apply to the Work.
187+
188+
9. Additional agreements
189+
190+
While distributing the Work, You may choose to conclude an additional
191+
agreement, defining obligations or services consistent with this Licence.
192+
However, if accepting obligations, You may act only on your own behalf and on
193+
your sole responsibility, not on behalf of the original Licensor or any other
194+
Contributor, and only if You agree to indemnify, defend, and hold each
195+
Contributor harmless for any liability incurred by, or claims asserted against
196+
such Contributor by the fact You have accepted any warranty or additional
197+
liability.
198+
199+
10. Acceptance of the Licence
200+
201+
The provisions of this Licence can be accepted by clicking on an icon ‘I
202+
agree’ placed under the bottom of a window displaying the text of this Licence
203+
or by affirming consent in any other similar way, in accordance with the rules
204+
of applicable law. Clicking on that icon indicates your clear and irrevocable
205+
acceptance of this Licence and all of its terms and conditions.
206+
207+
Similarly, you irrevocably accept this Licence and all of its terms and
208+
conditions by exercising any rights granted to You by Article 2 of this
209+
Licence, such as the use of the Work, the creation by You of a Derivative Work
210+
or the Distribution or Communication by You of the Work or copies thereof.
211+
212+
11. Information to the public
213+
214+
In case of any Distribution or Communication of the Work by means of
215+
electronic communication by You (for example, by offering to download the Work
216+
from a remote location) the distribution channel or media (for example, a
217+
website) must at least provide to the public the information requested by the
218+
applicable law regarding the Licensor, the Licence and the way it may be
219+
accessible, concluded, stored and reproduced by the Licensee.
220+
221+
12. Termination of the Licence
222+
223+
The Licence and the rights granted hereunder will terminate automatically upon
224+
any breach by the Licensee of the terms of the Licence. Such a termination
225+
will not terminate the licences of any person who has received the Work from
226+
the Licensee under the Licence, provided such persons remain in full
227+
compliance with the Licence.
228+
229+
13. Miscellaneous
230+
231+
Without prejudice of Article 9 above, the Licence represents the complete
232+
agreement between the Parties as to the Work.
233+
234+
If any provision of the Licence is invalid or unenforceable under applicable
235+
law, this will not affect the validity or enforceability of the Licence as a
236+
whole. Such provision will be construed or reformed so as necessary to make it
237+
valid and enforceable.
238+
239+
The European Commission may publish other linguistic versions or new versions
240+
of this Licence or updated versions of the Appendix, so far this is required
241+
and reasonable, without reducing the scope of the rights granted by the
242+
Licence. New versions of the Licence will be published with a unique version
243+
number.
244+
245+
All linguistic versions of this Licence, approved by the European Commission,
246+
have identical value. Parties can take advantage of the linguistic version of
247+
their choice.
248+
249+
14. Jurisdiction
250+
251+
Without prejudice to specific agreement between parties,
252+
— any litigation resulting from the interpretation of this License, arising
253+
between the European Union institutions, bodies, offices or agencies, as a
254+
Licensor, and any Licensee, will be subject to the jurisdiction of the Court
255+
of Justice of the European Union, as laid down in article 272 of the Treaty
256+
on the Functioning of the European Union,
257+
— any litigation arising between other parties and resulting from the
258+
interpretation of this License, will be subject to the exclusive
259+
jurisdiction of the competent court where the Licensor resides or conducts
260+
its primary business.
261+

264+
Without prejudice to specific agreement between parties,
265+
— this Licence shall be governed by the law of the European Union Member State

— this licence shall be governed by Belgian law if the Licensor has no seat,
268+
residence or registered office inside a European Union Member State.
